摘要

In a ball bearing for an automobile wheel hub comprising a double set of balls, the inner race is composed of two half-races to allow mounting of one of the two sets of balls. A first set of balls (2) is located between an outer race (3) and a facing portion of the hub (4). A second set of balls (5) is located between the outer race (3) and an inner half-race (6) fixed onto the hub (4). The inner half-race (6) is secured by an ring-like end portion (9) of the hub (4) folded by cold forming. A substantially flat washer (10) is interposed between said inner half-race (6) and the ring-like end portion (9).
