Self-aligning ball bearings have a spherical raceway in the outer ring with a center of curvature matched with the bearing center. This allows the inner ring, balls, and cage to rotate freely around the bearing center, maintaining alignment.
Advantages
Self-aligning ball bearings generate less friction than any other type of rolling bearing, which enables them to run cooler even at high speeds. Because of low heat generation, the bearing temperature is lower, leading to extended bearing life and maintenance intervals.
Main applications of self-aligning ball bearing：
Low noise motor, automobile, motorcycle, woodworking machinery, transmission shaft of textile machinery, mining machinery, mechanical and electrical equipment, plastic machinery, work equipment, medical equipment, fitness and sports equipment and general machinery, etc.
