Self-aligning ball bearings have two rows of balls and a common sphered raceway in the outer ring.
The bearings are insensitive to angular misalignment of the shaft relative to the housing.
Self-aligning ball bearings generate less friction than any other type of rolling bearing, which enables them to run cooler even at high speeds.
