ABSTRACT:
A combined radial and thrust bearing comprising: a radial rolling bearing including an outer ring provided with a large-diameter cylindrical portion the inner peripheral surface of which constitutes a raceway of rollers, a small-diameter cylindrical portion which extends from one end of the large-diameter cylindrical portion for carrying a thrust rolling bearing and which has a smaller diameter than the large-diameter cylindrical portion and a plurality of projections for preventing the thrust rolling bearing which is provided on the periphery at the end portion of the small-diameter cylindrical portion from coming off, and a plurality of rollers disposed on the inner peripheral surface of the outer ring and held by a retainer at regular circumferential intervals; and a thrust rolling bearing including axially arranged first race and second race, the first race being composed of an annular plate, a plurality of rollers disposed and held by an annular retainer at regular circumferential intervals and the second race being composed of an outer cylindrical portion and an annular plate portion, wherein the first race and the annular retainer of the thrust rolling bearing are placed over the small-diameter cylindrical portion of the radial rolling bearing, and each of the projections is engaged with the outer periphery of the opening of the retainer so as to prevent the thrust rolling bearing from coming off the radial rolling bearing. Assembly and processing of a combined radial and thrust bearing are facilitated and the performance thereof is increased.
