Self-aligning Ball Bearing

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