Self-aligning ball bearings

Self-aligning ball bearings have two rows of balls, the outer ring has a common spherical raceway, and the inner ring has two deep uninterrupted raceway grooves. They are available in open or sealed styles. The bearing is not sensitive to the angular misalignment of the shaft relative to the bearing seat. This misalignment may be caused by shaft deflection, etc. The optimized design of the self-aligning ball bearing better solves this problem.
