Self-aligning ball bearings have two rows of balls and a common sphered raceway in the outer ring. The bearings are insensitive to angular misalignment of the shaft relative to the housing.
Basic design bearings
Basic design self-aligning ball bearings are available with a cylindrical bore and, for certain sizes, with a 1:12 tapered bore (designation suffix K).

Self-aligning ball bearings with an extended inner ring are designed for less demanding applications that use commercial grade shafting.
