Approaches to Handling Old Slewing Bearings
In the process of industrial production, slewing bearings gradually age and get damaged due to long – term use of equipment, and become waste items. However, the handling of old slewing bearings is not simply about discarding them. Instead, it is an important topic involving aspects such as resource recycling, environmental protection, and economic benefits. Scientific and rational handling of old slewing bearings can reduce costs, achieve the recycling of resources, and minimize the negative impact on the environment.
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.
