Self-aligning ball bearings are a type of rolling bearing with a self-aligning function, capable of automatically compensating for deviations caused by shaft deflection or installation errors, and are widely used in machinery and equipment. Definition and Structure Self-aligning ball bearings are rolling bearings with an outer ring raceway that is spherical. Their main structure includes two inner rings and one outer ring, with the outer ring raceway being spherical and the inner ring having double raceways. This design allows self-aligning ball bearings to have a certain degree of relative tilt between the inner ring, outer ring, and balls without affecting normal operation.
