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.
JEV self-aligning ball bearings are available in several designs, including:
1.basic design bearings
2.bearings with an extended inner ring
3.sealed bearings
