Self-aligning ball bearing features:

1. Speed is high

2. With self-aligning feature

3. Poor rigidity, resistance to shock, poor vibration capability

 

Spherical outer ring raceway, with self-aligning properties, it can automatically adjust for shaft or housing deflection or misalignment of the axis caused by errors.

Self-aligning ball bearings mainly take radial load, axial load while subjected to a smaller. Axis (shell) of the axial displacement within the limits of limited clearance, with self-aligning properties, allowing the external conditions is relatively little inclination to work for support is not strictly guarantee seat hole concentricity of the parts. Self-aligning ball bearing outer ring raceway is processed into spherical shape, the inner raceway with two double row deep groove ball bearings, aligning performance. It is mainly used to bear radial load, radial load at the same time, it can withstand a small amount of axial load, but generally can not bear the pure axial load, the speed limit lower than the deep groove ball bearings. This kind of bearings are used for the load prone to bending under the double bearing shaft, and dual bearings coaxial holes can not guarantee that the parts in the strict, but the inner ring and outer ring center line of the relative steepness of the center line of not more than 3 degrees.
