Why can Four-Point Contact Ball Bearing be so popular in high-speed operation?

Four-Point Contact Ball Bearing adopts a split design, and its inner and outer ring raceways present a unique peach-shaped cross-section. This design allows the bearing to effectively cope with bidirectional axial loads while bearing radial loads. Under no load or pure radial load, four-point contact is formed between the steel ball and the ring, ensuring uniform distribution of contact points and stable load-bearing performance. In addition, the design of double semi-inner or outer rings increases the number of balls, further enhancing the bearing's load-bearing capacity.
Thanks to its compact structure and optimized design, Four-Point Contact Ball Bearing has a higher limit speed while maintaining consistent radial clearance. This enables it to maintain stable performance in high-speed operation occasions and meet various high-precision and high-speed application requirements. The bearing can withstand radial and bidirectional axial pressure at the same time and has good multi-directional load capacity. Even during high-speed rotation, it can maintain stable load-bearing performance to ensure the stable operation of mechanical equipment. Through reasonable contact angle design and automatic adjustment function, Four-Point Contact Ball Bearing can maintain low friction and wear during high-speed operation and improve operation smoothness. This helps reduce vibration and noise and improve the performance of the overall equipment. Bearings that have been treated with processes such as heat treatment have a higher operating temperature range and can maintain stable performance in high temperature environments. This allows it to play a good role in some special working conditions.
In high-speed operation, Four-Point Contact Ball Bearing shows its good performance. Its high limit speed ensures that the bearing will not overheat or fail when rotating at high speed; high load capacity and smooth operation ensure the stability and reliability of mechanical equipment under high-speed operation. In addition, the bearing also has a certain automatic adjustment function, which can automatically adjust the axial deviation and installation error to further improve the smoothness and accuracy of operation.
Due to its good performance and advantages, Four-Point Contact Ball Bearing is widely used in aerospace, industrial machinery, automobile manufacturing and other fields. In the field of aerospace, it undertakes the support and transmission tasks of key components such as engines and landing gears; in the field of industrial machinery, it becomes the core component of high-precision machine tools, humanoid robots and other equipment; in the field of automobile manufacturing, it helps cars achieve smooth driving and reliable power transmission.
