Claims

[Claims for Utility Model Registration] (1) Inner and outer annular bearing rings are each formed by curving, the surfaces facing each other serve as raceway surfaces, and a plurality of balls are rolled between the raceway surfaces of these inner and outer bearing rings. Each of the mutually opposing circumferential surfaces of the inner and outer bearing rings, excluding the raceway surface, is provided with a hook portion that protrudes toward the other side and is hooked to the ball in the axial direction. Features a non-separable shell type ball bearing. (2) The non-separable shell ball bearing according to claim 1, wherein the hook portion is formed by secondary processing of the raceway surface after curving the inner and outer raceway rings. (3) The non-separable shell ball bearing according to claim 1, wherein the hook portion is formed by plastic deformation of the end faces of the inner and outer bearing rings.
