The components of the self aligning ball bearing include two rows of balls, a cage, an inner ring, and an outer ring with a common concave sphered raceway.This type of bearings is self-aligning and insensitive to angular misalignments of the shaft relative to the housing. The bearings are produced in several design: open bearings with the basic design, sealed bearings, open bearings with an extended inner ring.The self alignning ball bearings have the lowest friction of all rolling bearings.Mini-series: 10x, 12x, 13x
 General Series: 12xx, 13xx, 22xx 23xx
 
 definitions of Self-aligning ball bearings:
