Why is the flanged slewing bearing so important?
Thanks to its unique structural design, the flanged slewing bearing integrates the slewing and load – bearing functions within a limited space. It is applied in many fields such as construction machinery, energy, special – purpose vehicles, port and ship, industrial automation, and robotics. It has the advantages of easy installation, precise positioning, strong load – bearing capacity, smooth operation, and good sealing performance. Moreover, it features high manufacturing precision and strong reliability.
What are the features of the flanged slewing bearing?
Flanged slewing bearing, with their unique structural design, achieve a compact layout. They can perfectly integrate the slewing motion and load – bearing functions within extremely limited space. This feature makes them widely used in equipment where space is at a premium, greatly enhancing space utilization. In terms of load – bearing capacity, through elaborate structural design and the use of strictly selected high – strength materials, they demonstrate excellent performance. They can easily handle strong axial forces, radial forces, and complex overturning moments, which is sufficient to meet the support and slewing requirements of various heavy – duty equipment under harsh working conditions.
From the perspective of precision, the manufacturing process of flanged slewing bearings is extremely strict. The processing accuracy of the raceways and rolling elements, as well as the final assembly accuracy, are all controlled within a very small error range. This enables them to maintain high – precision slewing motion during long – term and high – frequency use, laying a solid foundation for the precise processing and stable operation of equipment. In terms of reliability, high – quality materials, advanced manufacturing processes, and a reasonable internal structural design work together. Coupled with a perfect sealing and lubrication system, they can effectively resist the invasion of harsh working environments such as dust, moisture, and high temperatures, greatly reducing the probability of failures and thus significantly extending their service life.
In terms of installation and maintenance, their advantages are also prominent. The flanged is equipped with standard mounting holes. By using bolts, the slewing bearing can be quickly connected to other components of the equipment. The entire installation process is simple and efficient, which can greatly reduce the difficulty and cost of equipment installation. Moreover, due to their high degree of standardization, products of the same type and specification have good interchangeability. Once a failure occurs and maintenance or replacement is required, the operation can be completed quickly, effectively reducing equipment downtime and ensuring the continuity of production.
Flanged slewing bearings are widely used in the following fields:
Construction Machinery Field
Cranes: Truck cranes, crawler cranes, tower cranes, etc. The slewing bearing is installed between the chassis and the turntable. It withstands the huge axial forces, radial forces, and overturning moments when lifting heavy objects, ensuring the stable rotation of the turntable and enabling lifting operations in different directions.
Excavators: It is the core component for the rotation of excavators. It connects the rotating upper body to the chassis, allowing the excavator to flexibly perform operations such as excavation and loading.
Energy Field
Wind Power Generation: It is used between the hub and tower of wind turbines, on the rotating components of the main shaft and impeller, and in the yaw part of the nacelle. It withstands huge torques and axial loads, ensuring that the impeller can adjust its angle with the change of wind direction and improving power generation efficiency.
Solar Power Generation: In solar photovoltaic power generation systems, it can be used in tracking systems, enabling solar panels to rotate according to the position of the sun to obtain the best lighting angle.
Special – Purpose Vehicle Field
Concrete Pump Trucks: It plays a role in connecting the chassis and the boom of the pump truck. The boom can achieve multi – angle rotation through the slewing bearing, enabling the accurate delivery of concrete to various positions in construction sites.
Fire Trucks: In aerial ladder fire trucks, the aerial ladder is connected to the chassis of the fire truck through the slewing bearing, allowing it to rotate freely in the horizontal direction and quickly adjust to the best rescue position. The fire water cannon also uses the slewing bearing to achieve horizontal and vertical rotation, accurately spraying water to different positions at the fire scene.
Port and Ship Field
Port Cranes: Such as quay container cranes and portal cranes. The slewing bearing enables the boom or turntable of the crane to rotate 360 degrees, realizing the loading and unloading of ship cargo and improving the cargo handling capacity of the port.
Marine Cranes: Also known as floating cranes, they are installed on ships for lifting cargo or performing offshore operations. The slewing bearing ensures the stable rotation and operation of the crane on the ship, adapting to the complex working conditions at sea.
Industrial Automation and Robot Field
Industrial Robots: It is applied to the joints of welding robots, palletizing robots, handling robots, etc., enabling the arms or joints of the robots to rotate flexibly and perform various complex actions and operations, improving production efficiency and quality.
Automated Production Lines: It is used in some workbenches that require rotational motion and transfer parts of conveyor lines, realizing the accurate transfer of materials and the conversion of processing positions, and improving the degree of automation and coordination of the production line.
Flanged slewing bearings have the following advantages:
Easy Installation: The flanged is equipped with a series of bolt holes. Through bolts, the slewing bearing can be quickly fixed to other components of the equipment. The installation process is simple and efficient, which can shorten the equipment assembly time and improve the installation accuracy.
Precise Positioning: During installation, the flanged fits closely with related components, and the fitting accuracy is high. It can provide accurate positioning for the slewing components, ensuring that the axis of the slewing motion is consistent with the design requirements, which is conducive to improving the overall operation accuracy of the equipment.
Strong Load – Bearing Capacity: With a reasonable structural design, it can simultaneously withstand large axial forces, radial forces, and overturning moments, meeting the slewing support requirements of large – scale mechanical equipment such as cranes and excavators under heavy – load conditions.
Smooth Operation: The rolling elements and raceways inside are precisely matched, and the friction coefficient is small. During the slewing process, it can effectively reduce vibration and noise, and the operation is smooth, which is conducive to improving the working efficiency and service life of the equipment.
Good Sealing Performance: Usually, there are good sealing designs at the joints between the flanged and other components and inside the slewing bearing. It can effectively prevent the intrusion of dust, moisture, impurities, etc., avoiding the wear and corrosion of internal parts and ensuring the normal operation of the slewing bearing.
The Price of flanged slewing bearing?
There are many factors affecting the price of flanged slewing bearing. In terms of raw materials, using high – quality steel such as 42CrMo can improve the strength, toughness, and wear resistance of the product, but it also increases the cost. In terms of manufacturing processes, advanced and precise processing equipment and strict quality control processes can ensure that indicators such as dimensional accuracy and surface roughness reach a high level, but this will also increase the price. The size and specification of the product are also crucial. Large – sized, special – specification, or flanged slewing bearings with high load – bearing capacity requirements are difficult to produce, and their prices will also increase accordingly. Brand and manufacturer reputation cannot be ignored. Well – known brands invest a lot in research and development, production, and after – sales service. Their products are of reliable quality, and the prices are often higher. In addition, changes in market supply and demand will cause price fluctuations. When demand is strong and supply is tight, the price rises; otherwise, it falls.
