How to Prevent Rust from Damaging slew Bearings

The performance and lifespan of bearings are crucial to the operation of equipment. Rust poses a threat to the reliability and lifespan of bearings. Rust can damage the lubricating film, intensify friction, and affect the rotational accuracy and stability.

What is a Slewing Bearing?

A slewing bearing is an essential device that enables mechanical components to achieve rotational motion. It is widely used in various types of mechanical equipment. It typically consists of a slewing support, a drive device, a sealing system, etc. The slewing support, as a fundamental part, can withstand axial forces, radial forces, and overturning moments, ensuring the stable rotation of the equipment. The drive device provides power for rotation. Commonly, a combination of a motor and a reducer is used, which drives the slewing support to rotate through methods such as gear transmission. For example, in a tower crane, the rotation of the jib during operation relies on the slewing bearing. In the field of industrial robots, slewing bearings help robots move flexibly. It is the key to the normal operation of many large – scale and complex mechanical devices.

The Principle of Rust’s Damage to Bearings

Rust is essentially an iron oxide. When the iron on the surface of a slew bearing reacts chemically with oxygen and water in the air, rust is formed. Rust has a loose texture and a larger volume than iron, which can cause local stress concentration on the bearing surface and damage the bearing’s lubricating film. As rust continues to form and accumulate, it will intensify the internal friction of the bearing, raise the bearing temperature, and accelerate the aging and deterioration of the lubricant. At the same time, rust particles may become embedded between the rolling elements, raceways, and cages of the bearing, causing wear and pitting, which seriously affects the rotational accuracy and operating stability of the bearing.

Measures to Prevent Rust Damage

Material Selection

Choose Corrosion – Resistant Materials: During the design and selection stage, prioritize the use of corrosion – resistant bearing materials. For example, stainless – steel bearings have good corrosion – resistance and are suitable for working environments that are humid or contain corrosive gases or liquids. Common stainless steel materials such as 304 and 316 are used. Among them, 316 stainless – steel has better corrosion – resistance due to the addition of molybdenum, making it particularly suitable for use in harsh corrosion environments such as marine environments or chemical production.

Apply Surface Coating Materials: Surface coating treatment of bearings made of ordinary steel is also an effective way to improve their corrosion – resistance. Common coatings include galvanizing, nickel – plating, chromium – plating, etc. The galvanized layer can form a dense protective film on the bearing surface, effectively isolating oxygen and moisture. The nickel – plated layer can not only enhance the corrosion – resistance of the bearing but also improve its appearance quality and surface hardness. The chromium – plated layer has high hardness and wear – resistance, which can strengthen the anti – wear and anti – corrosion capabilities of the bearing surface.

Storage and Transportation

Control of Storage Environment: When storing bearings, place them in a dry and well – ventilated warehouse. The relative humidity of the warehouse should be kept at a low level, generally recommended to be no more than 60%. Dehumidifying equipment can be installed to maintain the stability of the humidity in the warehouse. At the same time, avoid placing bearings near windows, doors, or other locations where they are easily invaded by humid air. For bearings in long – term storage, it is best to use sealed packaging and place desiccants, such as silica gel desiccants, inside the packaging to further absorb the moisture in the package and prevent rust from forming.

Transportation Protection Measures: During the transportation of bearings, take good protective measures. Avoid exposing bearings directly to humid air. Sealed packaging boxes can be used for packaging. For bearings in long – distance transportation or sea transportation, to prevent the erosion of seawater moisture, anti – rust bags or anti – rust paper can be placed inside the packaging box. These anti – rust materials can release anti – rust gases, forming a protective film on the bearing surface to prevent rust. At the same time, pay attention to the bumps and collisions during transportation to prevent the bearing surface from being more prone to rust due to mechanical damage.

Installation and Use

Inspection and Treatment Before Installation: Before installing a bearing, carefully inspect its appearance to ensure that there are no rust marks or damages on the surface. If there are slight rust spots on the bearing surface, a special rust remover can be used for treatment. After rust removal, clean and lubricate the bearing with clean lubricating oil before installation. During the installation process, ensure that the installation tools and the installation environment are clean to avoid impurities from entering the bearing and scratching the bearing surface, which may cause rust.

Operation Environment Management: During the use of bearings, keep the operating environment of the equipment clean and dry. For equipment operating in humid environments, protective measures such as installing protective covers and sealing devices can be taken to prevent moisture and dust from entering the bearings. At the same time, regularly maintain and service the equipment, and promptly clean the dust and dirt on the equipment surface to avoid their accumulation and absorption of moisture, which may lead to rust on the bearings. In addition, control the temperature and humidity during the operation of the equipment to avoid the formation of condensate on the bearing surface due to excessive temperature changes.

Lubrication and Maintenance

Select Appropriate Lubricants: High – quality lubricants can not only reduce the friction and wear of bearings but also have anti – rust functions. Select appropriate lubricants according to the working conditions and environment of the bearings. In humid environments, lubricating greases with good anti – rust properties, such as lithium – based lubricating grease, can be selected. It has good water – resistance and anti – rust properties. For high – speed rotating bearings, lubricating oils with low viscosity and good anti – oxidation properties should be selected, and an appropriate amount of anti – rust additives should be added to enhance the anti – rust ability.

Regular Lubrication and Replacement: Lubricate the bearings regularly according to the equipment’s operating instructions. When adding or replacing lubricants, ensure that the old lubricants are completely removed to prevent impurities and moisture in the old lubricants from corroding the bearings. At the same time, pay attention to the service life of the lubricants and replace expired or deteriorated lubricants in a timely manner to ensure their anti – rust and lubrication performance.

Monitoring and Maintenance

Establish a Monitoring Mechanism: Utilize modern monitoring technologies such as vibration monitoring and temperature monitoring to understand the operating status of bearings in real – time. By analyzing vibration signals and temperature changes, it is possible to promptly detect whether there are abnormal wear or overheating phenomena in the bearings, and then determine whether factors such as rust affect the bearing performance. Once abnormalities are detected, take timely measures to deal with them.

Regular Maintenance and Inspection: Develop a reasonable maintenance and inspection plan and regularly disassemble and inspect the bearings. Check for rust marks on the bearing surface, wear conditions, and the state of the lubricant. For minor rust marks found, deal with them in a timely manner. For bearings with severe wear or rust, replace them in a timely manner to avoid causing greater damage to the equipment.

Preventing rust from damaging bearings requires taking comprehensive and effective measures from multiple aspects, including material selection, storage and transportation, installation and use, lubrication and maintenance, and monitoring and maintenance. Only in this way can the erosion of rust on bearings be minimized, the lifespan of bearings be extended, the normal and stable operation of mechanical equipment be ensured, the maintenance costs and downtime of equipment be reduced, and the production efficiency and economic benefits of enterprises be improved.

The Price of Slewing Bearings with Rust – Prevention Capabilities

The price of slewing bearings with rust – prevention capabilities is influenced by multiple factors. In terms of materials, using corrosion – resistant materials such as stainless steel and special alloys, or applying high – quality anti – rust coatings will increase the cost and thus raise the price. In terms of processing, high – precision machining and advanced surface treatment processes can improve rust – prevention performance and quality, but the large investment also drives up the price.

The Application of Recyclable Materials in Bearing Manufacturing

The bearing manufacturing industry is exploring the use of recyclable materials to achieve sustainable development. The application forms include the recycling and reuse of metals, plastics, and composite materials.

What is Slewing Bearing Using New Materials?

A slewing bearing using new materials is manufactured with materials possessing special properties, building upon traditional designs. For example, carbon fiber composite materials with high strength and low density can reduce its own weight while enhancing load – bearing capacity, making them suitable for weight – sensitive fields such as aerospace. Self – lubricating materials are also used. These materials eliminate the need for frequent lubricant addition, reducing maintenance costs and pollution. They are commonly used in slewing bearings for food processing machinery. These new materials enable slewing bearings to perform better in terms of accuracy, corrosion resistance, and service life, meeting the requirements of modern industry for high – performance, long – lasting, and low – maintenance equipment, and driving the renewal and upgrading of mechanical equipment in various industries.

Application Forms of Recyclable Materials in Bearing Manufacturing

Recycling and Reuse of Metal Materials

Metal materials play a significant role in bearing manufacturing. Steel is one of the most commonly used materials for bearing manufacturing. Scrap steel has a wide range of sources, such as scrapped automobiles and mechanical parts. By recycling this scrap steel and subjecting it to processes like sorting, smelting, and refining, steel that meets the requirements of bearing manufacturing can be obtained again. For instance, after smelting, the impurities in recycled scrap steel are removed, and its chemical composition is adjusted. Then, through processes like rolling, steel for bearing rings and rolling elements can be produced. This recycling and reuse method can not only reduce the environmental damage caused by iron ore mining but also lower the energy consumption in the steel production process.

In addition to steel, non – ferrous metals such as copper and aluminum are also used in bearing manufacturing, for example, in manufacturing components like cages. Waste copper and aluminum products, such as discarded electrical wires and cables, and aluminum cans, can be processed through specific recycling processes. Recycled copper, after refining to remove impurities, can be used to manufacture high – precision bearing cages. Its good electrical and thermal conductivity helps improve the performance of bearings. Recycled aluminum, after melting and processing, can be made into aluminum alloy cages, which have the advantages of light weight and high strength and play an important role in some bearing application scenarios with strict weight requirements.

Recycling and Utilization of Plastics and Composites

In modern Slew bearing manufacturing, plastics and composites are also widely used in manufacturing components such as seals and cages. Recycled plastics, such as discarded plastic bottles and pipes, can be processed into recycled plastic pellets through processes like crushing and granulation, and then used to manufacture bearing seals and some cages. For example, polyamide (PA) plastic is commonly used to make bearing cages. Recycled PA plastic can be re – processed and formed into cages with excellent performance after treatment.

The recycling of composites is relatively complex but also of great significance. Some high – performance bearings are made of carbon fiber – reinforced composite materials, which are high in strength and low in weight. For discarded carbon fiber composite products, the carbon fibers can be separated from the matrix materials through methods such as pyrolysis and chemical dissolution, and then reused to manufacture new composite components, or mixed with other materials to manufacture bearing components with slightly lower requirements, thus achieving the recycling of resources.

Challenges in Using Recyclable Materials

Material Performance Consistency Issues

Recyclable materials come from a wide range of sources with varying qualities, resulting in significant differences in their properties. For example, recycled scrap steel may contain different types and amounts of impurities. Even after refining, it is difficult for its chemical composition and mechanical properties to be exactly the same as those of virgin materials. These performance differences can affect the quality and reliability of bearings, such as causing uneven hardness and reduced fatigue life of bearings.

For plastics and composites, degradation and aging during the recycling process can change their properties. Recycled plastics may experience a decrease in molecular weight and a decline in mechanical properties, which poses challenges for manufacturing high – precision and high – performance bearing components. Ensuring the consistency of the performance of recycled materials is one of the key issues in the application of recyclable materials in bearing manufacturing.

Recycling Costs and Economic Benefits

Recycling recyclable materials and processing them into raw materials suitable for bearing manufacturing requires certain investment. This includes the costs of collection, transportation during the recycling process, as well as subsequent costs of sorting, smelting, refining, and processing. For example, the smelting process of recycling scrap steel consumes a large amount of energy and requires high – quality equipment, which increases the recycling cost.

In terms of economic benefits, if the cost of recycled materials is too high and the price advantage of the manufactured bearing products in the market is not obvious, enterprises may find it difficult to obtain sufficient profits. Therefore, enterprises need to comprehensively consider factors such as the selection of recycled materials, the optimization of recycling processes, and product pricing to find a balance between recycling costs and economic benefits.

Technical and Process Difficulties

The use of recyclable materials in bearing manufacturing requires corresponding technical and process support. Currently, the processing technologies for some recycled materials are not mature enough to meet the high – precision requirements of bearing manufacturing. For example, for waste metal materials containing multiple impurities, existing refining technologies may not be able to completely remove all impurities, affecting the purity and performance of the materials.

For the recycling of composites, the lack of efficient and low – cost separation technologies makes recycling difficult. In addition, processing recycled materials into components that meet the requirements of bearing manufacturing requires the improvement and innovation of existing manufacturing processes. For example, when using recycled plastics to manufacture bearing seals, new molding processes need to be developed to ensure the dimensional accuracy and sealing performance of the seals.

Strengthening Material Testing and Quality Control

Establish a strict material testing system to conduct comprehensive and detailed tests on recycled materials. Before recycled materials enter the production process, test their chemical composition, mechanical properties, impurity content, and other indicators, and classify and screen them according to the test results. For materials with significant performance differences, take corresponding treatment measures, such as secondary refining of recycled steel to adjust its chemical composition to meet the standards of bearing manufacturing.

During the production process, strengthen quality control and conduct strict quality inspections on bearing components manufactured using recycled materials. Through means such as non – destructive testing and performance testing, ensure that product quality meets the requirements. For example, conduct hardness testing and flaw detection on bearing rings, and conduct dimensional accuracy testing and fatigue life testing on rolling elements to promptly identify and address quality issues.

Optimizing Recycling Processes and Reducing Costs

Increase investment in the research and development of recycling processes and develop efficient and energy – saving recycling technologies. For example, the use of advanced smelting technologies such as electric arc furnace smelting can improve the smelting efficiency of waste metals and reduce energy consumption. Develop new plastic recycling and processing technologies, such as a combination of physical and chemical modification methods, to improve the performance of recycled plastics and reduce the impact of performance degradation on bearing manufacturing.

Enterprises can cooperate with recycling enterprises to establish stable recycling channels and reduce the procurement cost of recycled materials. Optimize the production process, improve production efficiency, and reduce cost waste in the processing of recycled materials and bearing manufacturing. Through large – scale production, reduce the production cost per unit product and improve economic benefits.

Promoting Technological Innovation and Cooperation

Bearing manufacturing enterprises should strengthen cooperation with scientific research institutions and universities to jointly carry out research on the technologies of using recyclable materials in bearing manufacturing. Develop new material processing technologies and manufacturing processes to solve key problems such as the performance consistency of recycled materials and separation technology difficulties. For example, use nanotechnology to perform surface treatment on recycled materials to improve their wear resistance and corrosion resistance; develop new composite material recycling and separation technologies to improve recycling efficiency and quality.

Enterprises within the industry should also strengthen communication and cooperation, share experiences and technical achievements in the application of recyclable materials, and jointly promote the development of the industry. By establishing industry standards and specifications, standardize the quality standards and manufacturing processes of recycled materials to promote the wide application of recyclable materials in bearing manufacturing.

The Price of Slewing Bearings

The price of slewing bearings is affected by multiple factors. Materials are crucial. Slewing bearings made of high – grade steel and special alloys have better strength and wear resistance, higher costs, and thus higher prices. For example, slewing bearings containing special alloys are more expensive than those made of ordinary materials. Processing accuracy is also important. High – precision processing requires advanced equipment and complex techniques, which increases costs and naturally makes the product price higher. Slewing bearings used in precision equipment generally have a relatively high price. The manufacturing process also affects the price. Advanced manufacturing processes can enhance performance but also increase costs and thus raise the selling price. In addition, market supply and demand have a significant impact on prices. When demand is high, prices rise; when demand is low, prices fall.

Slewing Drive Selection Guide

The slewing drive is a key device for achieving the slewing motion of components. It consists of components such as slewing bearings, drive units, and sealing systems. When selecting a slewing drive, multiple factors need to be considered comprehensively.

What is Slewing Drive?

A slewing drive is a device that can realize the rotational motion of mechanical components and plays a key role in various mechanical equipment. It typically consists of components such as a slewing bearing, a drive device, and a sealing system. The slewing bearing, as a fundamental part, can withstand axial forces, radial forces, and overturning moments, ensuring the stable rotation of the equipment. The drive device provides power for the rotational motion. Commonly, a combination of a motor and a reducer is used, which drives the slewing bearing to rotate through gear transmission or other transmission methods.

How to Select Suitable Slewing Drive

Load characteristics are the primary basis for selection. When different devices operate, the loads borne by the slewing drive vary significantly. Take a tower crane as an example. During operation, it not only has to bear the gravity of the jib and the lifted load but also has to deal with complex external forces such as wind load and inertial force, which belongs to a heavy – load working condition. Such equipment requires a slewing drive with a strong load – bearing capacity. The rolling elements and raceways inside usually adopt high – strength materials to ensure stable operation under heavy loads and resistance to damage. In contrast, for small material transfer equipment on an automated production line, the load on the slewing drive is relatively light, and more emphasis is placed on the flexibility and accuracy of operation. A compact and lightweight model can be selected. When making a selection, it is necessary to accurately calculate the magnitude, direction, and acting point of the load to determine the required axial force, radial force, and overturning moment – bearing capacity of the slewing drive, avoiding equipment failures or premature wear caused by inaccurate load estimation.

Rotational accuracy determines the operating precision of the equipment. In precision machining equipment, such as the rotary table of a CNC machining center, a high – precision slewing drive is the core to ensure machining accuracy. Even a slight rotational error can lead to dimensional deviations and increased surface roughness of the machined parts. Such equipment has extremely high requirements for the rotational accuracy of the slewing drive. Generally, products equipped with high – precision bearings and manufactured and assembled through sophisticated processes should be selected to strictly control the radial run – out and axial play errors. For ordinary material handling equipment with less stringent accuracy requirements, the rotational accuracy standard can be appropriately relaxed, and a more cost – effective slewing drive can be selected. Therefore, before making a selection, it is necessary to clearly define the accuracy requirements of the equipment and then screen products with matching rotational accuracy according to the requirements, preventing cost increases due to excessive pursuit of high accuracy or performance degradation due to insufficient accuracy.

The speed requirement is also an important consideration in the selection process. The speed of the slewing drive directly affects the production efficiency of the equipment. In high – speed centrifugal separation equipment, the slewing drive needs to have high – speed performance to meet the needs of rapid material separation. This requires a reasonable internal structure design of the slewing drive to reduce friction and resistance during rotation. At the same time, appropriate lubrication methods and heat dissipation measures should be selected to ensure stable operation at high speeds. Conversely, in some large – scale port cranes and other equipment, although the load is large, the speed is not high, and more emphasis is placed on the low – speed stability of the slewing drive. Therefore, when making a selection, it is necessary to choose a slewing drive that can operate stably within the equipment’s working speed range and meet the power requirements, avoiding problems such as increased heat and wear caused by excessive speed or unstable operation at low speeds.

Working environment factors cannot be ignored. In harsh industrial environments, slewing drives face many challenges. In high – temperature environments, such as next to smelting furnaces in the metallurgical industry, the slewing drive needs to have good high – temperature resistance. Its materials and seals should be able to adapt to high – temperature working conditions to prevent oil deterioration and seal failure. In humid or corrosive environments, such as in marine engineering equipment, the slewing drive is prone to corrosion. Products with anti – corrosion coatings and made of anti – corrosion materials should be selected to extend the service life. In dusty environments, such as in mining machinery, the slewing drive needs to have a reliable dust – proof sealing structure to prevent dust from entering the interior and aggravating wear. Therefore, before making a selection, it is necessary to understand the working environment of the equipment in detail and select a slewing drive that can adapt to the corresponding environmental conditions to ensure the continuous and stable operation of the equipment in harsh environments.

Cost – effectiveness is also a key factor to be considered in the selection process. The purchase cost is an obvious influencing factor. The prices of slewing drives with different brands, specifications, and performances vary significantly. On the premise of meeting the equipment performance requirements, products with high cost – effectiveness should be selected as much as possible to avoid cost waste caused by blindly pursuing high – end products. However, it is also not advisable to only focus on low – price products and ignore product quality and performance. Some low – price products may save the purchase cost in the short term, but due to poor quality, they frequently malfunction, increasing maintenance costs and downtime, which instead reduces the overall economic benefits. Long – term operating costs, such as energy consumption and maintenance costs, also need to be considered. Energy – efficient slewing drives may have a relatively high initial purchase cost, but they can save a large amount of electricity costs in the long – term use. Products with simple maintenance and low component replacement costs can effectively reduce the equipment’s maintenance costs.

The Price of Slewing Drive

The price of slewing drives is influenced by multiple factors. Materials are a key factor. Using high – quality steel and special alloys can improve strength and wear resistance, increasing costs and thus raising the price. For example, slewing drives made with special alloys are more expensive than those made with ordinary materials. Processing accuracy is also important. High – precision processing requires advanced equipment and complex techniques, increasing costs and making the product price higher. The slewing drives used in precision equipment generally have a relatively high price. The manufacturing process also affects the price. Advanced manufacturing processes can optimize performance but also increase costs and thus raise the selling price.

Differences between Gear and Gearless Slewing Drives

Slewing supports are of great significance to the rotating function of mechanical equipment. There are significant differences between geared and gearless slewing supports. The former is used in heavy – load equipment, while the latter is applied in fields with high requirements for accuracy, noise, and space.

What is a Gear Slewing Drive?

A gear slewing drive integrates a gear transmission system within its structure. These gears are typically installed on the inner or outer ring of the slewing drive and, in conjunction with external drive devices such as motors and reducers, facilitate rotational motion. The presence of gears endows the gear slewing drive with unique advantages. In terms of transmission characteristics, it can provide high torque output, making it suitable for applications that require heavy – load drive and precise rotational positioning. For instance, in large – scale port cranes, the weight of lifted loads can reach dozens or even hundreds of tons. The gear slewing drive, with its powerful torque – transmitting capacity, can stably drive the rotating part of the crane, ensuring that the heavy loads are accurately hoisted to the designated position. Moreover, gear transmission offers high efficiency, effectively transferring power to the slewing drive, reducing energy losses, and enhancing the operational economy of the equipment.

What is Slewing Drive?

In contrast, a slewing drive dispenses with the traditional gear – based transmission structure. It generally achieves rotational motion through means such as friction, magnetism, or hydraulics. This design confers unique advantages to the slewing drive in certain aspects. Structurally, without the complex gear system, its overall structure is more compact and space – saving. This feature is highly advantageous in equipment with stringent space – layout requirements. For example, in small rotating worktables on industrial automation production lines, the slewing drive can achieve efficient rotation within a limited space, enhancing the integration and compactness of the equipment. Additionally, slewing drives generate less noise and vibration during operation, which is of great significance for equipment that demands high operational stability and quietness, such as precision instruments and medical equipment.

Differences between Geared and Gearless Slewing Drives

When considering accuracy, a geared slewing drive can achieve high rotational accuracy if its design and manufacturing precision are sufficient. However, the inevitable backlash in gear transmission can affect rotational accuracy to some extent, especially in working conditions that involve frequent start – stop operations and require high – precision positioning. On the other hand, gearless slewing drives, particularly those incorporating advanced magnetic levitation or hydrostatic support technologies, can achieve near – zero – clearance rotational motion, attaining extremely high rotational accuracy. This makes them suitable for industries with exacting precision requirements, such as semiconductor manufacturing equipment.

There are also significant differences in maintenance and cost. Geared slewing drives, due to their gear systems, require more complex maintenance tasks, including gear lubrication, wear monitoring, and replacement. Gears are prone to issues like wear and fatigue during long – term operation under the influence of loads and friction, necessitating regular inspections, maintenance, and even component replacements. This increases the equipment’s downtime and maintenance costs. In contrast, gearless slewing drives have a simpler structure without complex gear – drive components. Their maintenance mainly focuses on checking the support components and drive systems, resulting in relatively lower maintenance difficulty and costs. Nevertheless, some gearless slewing drives that employ advanced technologies, such as magnetic – levitation slewing drives, have high manufacturing costs, which offset part of the maintenance – cost advantage to a certain extent.

Regarding application scenarios, geared slewing drives are widely used in heavy – load industrial equipment, such as large – scale excavators in mining machinery and tower cranes in construction machinery. These devices need to withstand substantial weights and loads, and the powerful torque – transmitting ability and good stability of geared slewing drives ensure the safe and reliable operation of the equipment. Gearless slewing drives are more suitable for fields with high requirements for accuracy, noise, and space, such as electronic manufacturing equipment, optical instruments, and medical imaging devices. In these areas, the equipment demands extremely high rotational accuracy and a quiet and stable operating environment, allowing the advantages of gearless slewing drives to be fully realized.

Price of the Two Types of Slewing Drives

The prices of both geared and gearless slewing drives are influenced by numerous factors. Materials are a key determinant. Drives made from high – grade steel or special alloys have higher costs and thus higher prices. Using special materials for gears further increases the price. Processing precision also matters significantly. High – precision processing requires advanced equipment and complex techniques, driving up costs and, consequently, product prices. The gear precision in geared slewing drives and the rotational precision in gearless slewing drives both affect the price. Manufacturing processes also play a role. Advanced manufacturing processes can enhance performance but also raise costs.

Approaches to Handling Old Slewing Bearings

The disposal of old slewing supports is related to resource recovery, environmental protection and economic benefits. Old slewing supports are components replaced from equipment for various reasons. They have various problems and can be treated differently according to the degree of wear.

What are Old Slewing Bearings?

An old slewing bearing refers to a slewing bearing component that has been used on mechanical equipment and is replaced due to reasons such as long – term operation, wear and tear, aging, or equipment upgrading. A slewing bearing itself is a mechanical component that can withstand comprehensive loads and enable relative slewing motion. It is commonly found in equipment such as cranes, excavators, and port machinery. Old slewing bearings may have problems such as worn raceways, damaged rolling elements, and aged seals, which lead to a decline in accuracy and performance, making them unable to meet the normal operation requirements of the equipment. However, after evaluation, some old slewing bearings can be reused through repair and renovation, while those with severe wear are subject to material recycling to achieve resource circulation.

Slightly Worn Slewing Bearings

There are various ways to recycle and reuse old slewing bearings. For slewing bearings with slight wear and an intact structure, they can be rejuvenated through repair and renovation. First, the slewing bearing is completely disassembled and cleaned, and each component is carefully inspected for wear and deformation. For the worn raceways and rolling elements, professional grinding and quenching processes are used for repair to restore their dimensional accuracy and surface hardness. After renovation, the slewing bearings are subject to strict quality inspection. Once all performance indicators meet the standards, they can be reused in equipment with relatively lower accuracy requirements, such as small – scale construction machinery and material handling equipment. This can not only significantly reduce the equipment procurement cost but also reduce the energy consumption and environmental pollution during the production of new slewing bearings.

Severely Worn Slewing Bearings

For old slewing bearings with severe wear that cannot be repaired, material recycling is the main treatment approach. Slewing bearings are mostly made of steel. They can be disassembled and recycled separately. Through professional mechanical disassembly equipment, components such as the inner and outer rings, rolling elements, and cages of the slewing bearing are separated, and the oil stains and impurities on the surface are removed. The sorted steel can be remelted in a furnace to make new steel products, which are used to manufacture various mechanical parts, building materials, etc. In addition to steel, some slewing bearings may contain non – ferrous metals such as copper and zinc. Specific separation technologies can be used to separate these non – ferrous metals, which can also achieve recycling and improve the comprehensive utilization rate of resources.

Other Methods for Handling Slewing Bearings

When handling old slewing bearings, the remanufacturing of their components can also be considered. Components on old slewing bearings that still have usability, such as some unworn rolling elements and seals, can be cleaned, inspected, and re – processed, and then reassembled into new slewing bearings or used for the repair of other equipment. This approach can not only make full use of the remaining value of old slewing bearings but also reduce the production of new components, thereby reducing production costs and resource consumption.

Problems in Handling Old Slewing Bearings

When handling old slewing bearings, environmental protection issues cannot be ignored. Pollutants such as oil stains and lubricating oil generated during the disassembly process need to be properly treated. Special oil – stain treatment equipment is used to collect the oil stains, and the oil and water are separated through oil – water separation technology. The separated oil can be recycled, and the wastewater needs to be treated to meet the environmental protection discharge standards before it can be discharged. In addition, measures should be taken to control the noise and dust generated during the disassembly and recycling process, such as setting up sound – insulation facilities in the operation area and installing dust collection devices, to reduce the impact on the surrounding environment and personnel.

To effectively handle old slewing bearings, industry collaboration and standard – setting are of great significance. Manufacturers, users, and recycling and treatment enterprises of slewing bearings should strengthen cooperation and establish a complete recycling system. Manufacturers can provide technical support and guidance for the recycling of old slewing bearings. Users should promptly deliver waste slewing bearings to recycling and treatment enterprises, and recycling and treatment enterprises should use professional technologies and equipment for efficient processing. At the same time, relevant departments should formulate unified recycling and treatment standards and specifications for old slewing bearings, clarify the treatment process, quality requirements, and environmental protection standards, and strengthen the supervision of recycling and treatment enterprises to ensure that the treatment process of old slewing bearings complies with the regulations and achieves the dual goals of resource recycling and environmental protection.

Handling old slewing bearings is a complex and important task that covers multiple aspects such as recycling and reuse, environmental protection measures, and industry collaboration. Through scientific and reasonable handling methods, the maximum utilization of resources can be achieved, environmental pollution can be reduced, and strong support can be provided for the sustainable development of the industry. With the continuous progress of technology and the improvement of people’s environmental awareness, it is believed that the handling of old slewing bearings will be more efficient and environmentally friendly in the future, contributing more to the construction of a resource – saving and environment – friendly society.

The Price of Slewing Bearings

The price of slewing bearings is affected by multiple factors. Materials are crucial. Slewing bearings made of high – grade steel and special alloys have better strength and wear resistance and are more expensive. Processing accuracy is also important. High – precision processing requires high – end equipment and advanced technology, increasing costs and thus raising the product price. Market supply and demand also affect prices. When the demand from industries such as construction and wind power is high, resulting in a shortage of supply, the price rises. When the demand is weak and the supply is excessive, the price drops. In addition, brand value and the quality of after – sales service can also influence the price of slewing bearings to a certain extent.

Why Lubricating Oil Is Important for Slewing Bearings

In the vast system of industrial machinery, lubricating oil and bearings, although seemingly minor components, play a crucial role. They are the core elements ensuring the stable and efficient operation of machinery.

What is a Slewing Bearing?

Slew Bearing, as the hubs of mechanical operation, are responsible for supporting and guiding rotating or oscillating components. There is a wide variety of slew bearings. From common deep – groove ball slew bearings to tapered roller slew bearings suitable for heavy loads, different types meet the specific requirements of various machines. For example, in an automotive engine, the crankshaft slew bearing has to withstand huge pressure and high – speed rotation. Its precision and reliability directly affect the engine’s performance. In precision instruments, miniature slew bearings need to ensure minimal friction and high – precision operation.

What is Lubricating Oil?

Lubricating oil is like the “blood” of machinery and is crucial for the normal operation of slew bearings. Its primary function is to reduce friction. When a slew bearing is in operation, the lubricating oil forms an oil film between the rolling elements and the raceway. This transforms the direct metal – to – metal friction into the internal friction of the oil film, greatly reducing friction, minimizing wear, and extending the slew bearing’s service life. Take the motor slew bearing as an example. Good lubrication can reduce energy consumption and improve the motor’s efficiency.

Functions of Lubricating Oil

Lubricating oil also has a heat – dissipation function. During the operation of a slew bearing, heat is generated due to friction. If the heat cannot be dissipated in time, a continuous increase in temperature will affect the slew bearing’s precision and material properties, and may even cause the slew bearing to seize. The lubricating oil can absorb heat during the circulation process and transfer it to the surrounding environment, maintaining the normal operating temperature of the slew bearing. For example, the gearbox slew bearings of large – scale wind turbines generate a large amount of heat under high – load operation, and a dedicated lubricating oil cooling system is essential.

In addition, lubricating oil can also act as a seal and anti – rust agent. It can fill the gaps in the slew bearing, preventing the intrusion of external dust, moisture, and other impurities and protecting the internal structure of the slew bearing. At the same time, the anti – rust additives in the lubricating oil can form a protective film on the metal surface, preventing the slew bearing from rusting and corroding, ensuring its stable operation in harsh environments, such as the slew bearings of mechanical equipment by the sea.

To achieve the best combination of lubricating oil and slew bearings, it is necessary to select the appropriate lubricating oil according to the type of slew bearing and working conditions. High – speed slew bearings are suitable for low – viscosity lubricating oil, which can reduce the stirring resistance. Heavy – load and low – speed slew bearings require high – viscosity lubricating oil with excellent extreme – pressure resistance to ensure the strength of the oil film. For example, low – viscosity precision machine tool oil is selected for the high – speed spindle slew bearings of machine tools, while high – viscosity lubricating oil with special anti – wear additives is used for the large heavy – load slew bearings of mining machinery.

At the same time, the correct lubrication method is also of great importance. Common lubrication methods include oil bath lubrication, splash lubrication, oil injection lubrication, and grease lubrication. Oil bath lubrication is suitable for medium – and low – speed slew bearings, where the slew bearing is partially immersed in oil for lubrication. Splash lubrication relies on rotating components to splash oil onto the slew bearing. Oil injection lubrication is used for high – speed, heavy – load, and important slew bearings, and oil is supplied precisely through an oil injection nozzle. Grease lubrication is often used for small, low – speed, and hard – to – lubricate slew bearings, using lubricating grease for lubrication.

In practical use, it is also necessary to regularly check the condition of the lubricating oil and the operation of the slew bearing. The lubricating oil will gradually age and become contaminated during use, and its performance will decline. Therefore, it needs to be replaced regularly. By checking the wear and clearance changes of the slew bearing, problems can be detected in a timely manner, and maintenance or replacement can be carried out to effectively avoid equipment failures and ensure the continuity of production.

Lubricating oil and slew bearings are interdependent and jointly safeguard the stable operation of machinery. In today’s continuously developing industry, in – depth research and rational application of lubricating oil and slew bearing technologies are of great significance for improving mechanical performance, reducing energy consumption, and extending the service life of equipment. They are a key link in promoting the efficient development of the industry.

The Price of Slewing Slew bearings

The price of slewing slew bearings is affected by many factors. Material is a key factor. Slewing slew bearings made of high – quality steel and special alloys have better strength and wear resistance and are more expensive. For example, those made of high – grade alloy steel are more expensive than those made of ordinary steel. Processing precision is also very important. High – precision processing requires advanced equipment and sophisticated technology, which can ensure slewing accuracy and reduce vibration. Accordingly, the cost and selling price are also high. When the demand from industries such as construction and wind power is high and the supply is insufficient, the price rises. If the demand is weak and the supply is excessive, the price will fall.

The Importance of Sealing in Slewing Bearings

The sealing technology of slewing supports is of great significance to the operation and lifespan of equipment. It ensures the normal operation of components by preventing the intrusion of pollutants and the leakage of lubricating oil.

What is the Sealing of a Slewing Bearing?

Slewing bearings are widely used in mechanical equipment such as cranes, excavators, and wind turbines. During operation, they need to withstand complex loads and harsh working environments. As an important part of slewing bearings, sealing technology mainly serves to prevent external pollutants such as dust, moisture, and impurities from entering the interior of the slewing bearing and to prevent the leakage of internal lubricating oil, thereby ensuring the normal operation of various components of the slewing bearing and extending the service life of the equipment.

The Principle of Slewing Bearing Sealing Technology

The sealing principle of slewing bearings is mainly based on preventing or reducing the leakage and intrusion of substances. Sealing devices usually form an effective sealing barrier at key parts such as between the inner and outer rings of the slewing bearing and between the rolling elements and the raceways to achieve the sealing function.

Take contact – type seals as an example. The seal contacts the slewing components tightly, and the elastic deformation of the seal is used to fill the gaps, preventing external pollutants from entering and internal lubricating oil from leaking. Non – contact – type seals, on the other hand, achieve sealing by setting up special structures, such as labyrinth – type structures. By utilizing air resistance and multiple barriers, it is difficult for pollutants to enter the interior of the slewing bearing, and at the same time, the leakage of lubricating oil is reduced.

Types of Slewing Bearing Seals

Contact – Type Seals

Lip – Seal: The lip – seal is one of the most common types of contact – type seals, usually made of elastic materials such as rubber. It has one or more lips that fit tightly against the surface of the slewing component to form a seal. The advantages of the lip – seal are its simple structure and good sealing performance, which can effectively prevent pollutants such as dust and moisture from entering the interior of the slewing bearing. However, during high – speed rotation, the friction between the lip and the slewing component is relatively large, which can easily cause wear of the seal and reduce the sealing life.

– O – Ring Seal: The O – ring seal is a circular rubber seal installed in a sealing groove. It achieves sealing through its own elastic deformation. The O – ring seal has good sealing performance, can withstand a certain pressure, and is easy to install with a low cost. However, in high – temperature, high – pressure, or chemically corrosive environments, the performance of the O – ring may be affected, leading to seal failure.

Non – Contact – Type Seals

– Labyrinth Seal: The labyrinth seal creates a labyrinth – like passage by setting up a series of interlaced grooves and protrusions between the inner and outer rings of the slewing bearing. When pollutants attempt to enter the interior of the slewing bearing, they need to pass through a tortuous path. During this process, the pollutants are blocked by air resistance, and most of them are blocked outside the labyrinth, thus achieving sealing. The advantages of the labyrinth seal are no contact friction, suitability for high – speed rotation, and a long service life. However, its sealing effect is relatively weak, and its ability to block fine particles is limited.

– Centrifugal Seal: The centrifugal seal uses the centrifugal force generated by the high – speed rotation of the slewing component to throw away the pollutants near the sealing part, thereby achieving the purpose of sealing. This sealing method is usually used in combination with other sealing methods to improve the overall sealing performance. The centrifugal seal has a good sealing effect when the rotation speed is high and the pollutant particles are large, but it has a poor sealing effect for low – speed rotation or fine particles.

The Impact of Sealing Technology on Equipment Performance

Impact on the Service Life of the Slewing Bearing

Good sealing technology can effectively prevent external pollutants from entering the interior of the slewing bearing, reducing the wear and corrosion of components such as rolling elements and raceways, thus extending the service life of the slewing bearing. Conversely, if the seal fails and pollutants such as dust and moisture enter the interior of the slewing bearing, it will intensify the wear of the components and cause the slewing bearing to be damaged prematurely.

Impact on the Operating Stability of the Equipment

The quality of the sealing technology directly affects the operating stability of the equipment. When poor sealing leads to the leakage of lubricating oil, the lubrication effect between the components of the slewing bearing will deteriorate, resulting in additional friction and vibration, which affects the normal operation of the equipment. In addition, the entry of pollutants into the interior of the slewing bearing may also cause changes in the gaps between the components, further affecting the operating accuracy and stability of the equipment.

Impact on the Equipment Maintenance Cost

Effective sealing technology can reduce the frequency and cost of equipment maintenance. For slewing bearings with good sealing, the internal components are less polluted, and there is no need for frequent maintenance work such as cleaning and replacement of components. However, for slewing bearings with seal failure, not only frequent maintenance is required, but it may also be necessary to replace the entire slewing bearing due to component damage, thus increasing the equipment maintenance cost.

The sealing technology of slewing bearings is a key factor in ensuring the normal operation of equipment and extending its service life. Different types of sealing technologies have their own advantages and disadvantages. In practical applications, it is necessary to comprehensively select the appropriate sealing method according to factors such as the working environment, rotation speed, and load of the slewing bearing. At the same time, with the continuous development of science and technology, new sealing materials and sealing structures are constantly emerging. Relevant technicians should pay close attention to the development trends of sealing technology and continuously optimize the sealing design to improve the sealing performance of slewing bearings and further enhance the overall performance and reliability of the equipment.

The Price of Slewing Bearings

There are many factors that affect the price of slewing bearings. Firstly, the type and structure, such as different structures like single – row, double – row, or triple – row roller types, have price differences due to different design and manufacturing complexities. Secondly, the accuracy grade is crucial. High – precision slewing bearings are more difficult to process and thus more expensive. Moreover, the choice of materials has a significant impact. Slewing bearings made of high – quality alloy steel or special materials have high costs and correspondingly higher prices. Finally, market supply – and – demand relationships can cause price fluctuations. When supply is in short supply, prices rise, and when there is an oversupply, prices may fall.
