Self Aligning Ball Bearing has two rows of balls and a common sphered raceway in the outer ring. The Bearing is consequently self-aligning and insensitive to shaft deflections and angular misalignment of the shaft relative to the housing. The Bearing is available with either a cylindrical or tapered bore. The Self Aligning Ball Bearing comes with a tapered bore that can be mounted directly on a shaft or on an adapter or withdrawal sleeve.
