Self-aligning Ball Bearings

The trajectory of the outer ring of this plastic bearing is spherical. Because the center of curvature corresponds to the center of the bearing, the inner ring, the ball and the retainer may freely rotate around the bearing center, and thus they are self-aligning.

Self-aligning Ball Bearings are being increasingly used in the latest, most sophisticated devices nowadays (as often as deep-groove bearings).
