Self-aligning ball bearings

The self-aligning ball bearing has two rows of balls, the outer ring has a common spherical raceway, and the inner ring has two deep uninterrupted raceway grooves. They can be opened or sealed. The bearing is not sensitive to the angular deviation of the shaft relative to the housing, which may be caused by shaft deflection.
