ABSTRACT:
A sealed ball bearing of the present invention is provided with an inner race having an inner raceway track, an outer race having an outer raceway track and being arranged so as to be concentric with the inner race, a plurality of balls arranged so as to be rollable between the inner and outer raceway tracks, holding grooves formed on edge portions of the outer race over an inner circumference of the outer race, and seal plates formed into annular shapes and held by the holding grooves, in which each of the seal plates includes a reinforcing plate and an elastic member bonded on one surface of the reinforcing plate, and the elastic member includes an elastic projection projected at an outer circumferential end portion thereof from an end portion of the reinforcing plate on the side of the outer race. The elastic projections are forced-into the respective holding grooves, so that the sealed ball bearing allows the seal plates to be supported on the inner race by the holding grooves without particularly complicating the shapes of or increasing the widths of the holding grooves and the elastic projections.
