High Speed Self-Aligning Ball Bearing , Double Row Bearings Product Description Self-aligning ball bearing(2301) has two rows of balls and a common sphered raceway in the outer ring. The bearings are consequently self-aligning and insensitive to shaft deflections and angular mis-alignment of the shaft related to the housing. Moreover, self-aligning ball bearing generates less friction than any other type of rolling bearings, which enables them to run cooler even in high
