ABSTRACT:
In a bearing including an inner race and an outer race disposed concentrically, a plurality of rolling members interposed between the two races, and two ring members of synthetic resin axially spaced on the outer peripheral surface of the outer race and wherein a rotating member is inserted in the inner race and the outer race is fitted and held in a non-rotating member through the ring members, two circumferential grooves are provided at an interval in the outer peripheral surface of the outer race. Each of the circumferential grooves comprises a first portion located toward a respective axial end of the outer race and whose bottom surface comprises an arcuate surface of a single radius, and a second portion located more toward the opposite axial end than the first portion and being narrower and shallower than the first portion. The first and second portions are formed continuously to each other, the ring members are closely held in the respective circumferential grooves by injection-molding synthetic resin, and the outer peripheral surface of each of the ring members protrudes radially outwardly more than the outer peripheral surface of the outer race.
