The double-row self-adjusting ball bearing has two rows of balls and a common spherical raceway in the outer ring
This allows the bearing to set itself and is insensitive to misalignment with respect to the bearing housing
This bearing is particularly suitable for bearing constructions where significant shaft deflections or misalignments must be taken into account
Another advantage of self-aligning ball bearings is that they have the lowest friction of all rolling bearings, so this bearing generates less frictional heat even at higher speeds
