PURPOSE:To facilitate manufacturing and assembling of a bearing by a method wherein projections arranged at one end of an inner race are fitted to concave grooves arranged at both axial ends of an outer race so as to position and fix the inner and outer races to each other. CONSTITUTION:An inner race 10 having a desired number of rotary bodies 4 assembled in the rotary body circulation passages 8 and 9 is inserted into an outer race 1 at one end thereof, projections 15 at the projected part 11 of the inner race 10 are press fitted to the axial end concave grooves 14 of the outer race 1, and thereby the inner and outer races are integrally positioned and fixed. Assembling of the inner race 10 to the outer race 1 can be performed such that the inner race 10 can be assembled from one of the sides of the outer race 1 under an arrangement of the concave grooves 14 at both ends of the outer race 1. |
