The outer ring raceway is spherical, with its center of curvature on the bearing axis. It can compensate for the alignment error between the shaft and the bearing housing, and adapt to a certain degree of deflection (the relative inclination between the inner and outer rings should not exceed 3 degrees). When the shaft or housing is deflected, it can automatically adjust without increasing the bearing load.
It can withstand relatively large radial loads and a certain amount of axial loads, but it cannot withstand moment loads. With a small contact angle, its axial load-bearing capacity is relatively small, while its radial load-bearing capacity is large.
Thanks to its excellent self-aligning ability, it can operate stably under complex conditions such as shaft deflection and misalignment. This significantly enhances the stability and reliability of equipment operation, reduces abnormal wear and failures caused by misalignment issues, and extends the service life of the equipment.
The rolling contact design results in a relatively small friction torque, which can improve the transmission efficiency and reduce the energy consumption during equipment operation. Even at high speeds, the temperature rise is relatively low.
It can effectively reduce the noise and vibration levels during equipment operation. For example, it can reduce the noise and vibration of fans.
In high-load and frequently vibrating equipment such as those in the metallurgical and mining machinery industries, its self-aligning performance can reduce the wear caused by high-intensity operations and improve the stability of the equipment.
It is used in the automotive transmission system and suspension system to reduce the load impact caused by uneven roads, enhancing driving safety and comfort.
In precision processing equipment and instrumentation, it can reduce the misalignment problems caused by thermal expansion and contraction, improving the quality of product processing.
