ABSTRACT:
A hub-bearing unit (10) for the wheel of a motor vehicle includes a hub (11) with a radial flange (13) and a central tubular portion (12) having an outer cylindrical surface (12a), and a bearing unit (15) with a dual set of rolling elements (16, 17) radially interposed between an outer, stationary bearing race (18) and first and second radially inner bearing races (19, 20) located side to side on the cylindrical outer surface (12a) of the tubular portion (12) of the hub. The hub forms a conical shoulder surface (21) diverging in an axially outer direction, and the first inner bearing race (19) has a conical surface (22) abutting against the conical shoulder surface (21) of the hub.
