Abstract
The assembly (10) includes at least one rolling bearing unit (20) having an outer race (21) and an inner race (22) rotatable relative to the outer race, and to annular bodies of plastic material (30, 40) overmoulded on the outer race (21) and the inner race (22), respectively, of the bearing unit. At least one of the two annular bodies (30, 40) has a free cylindrical surface (41). One of the two bearing races (21 or 22) forms a radially extending flange (25) having a cylindrical end surface (26), circumferentially continuous or discrete, which ends flush with the free cylindrical surface (41) of plastic material.
