A bearing assembly (10) provided with a rolling bearing unit (20) having an outer ring (21) provided with a centring flange (21f) with a peripheral edge (27) and an inner ring (22) provided with a relevant centring flange (22f) with a relevant peripheral edge (28) with a contact configuration for rolling elements, a plastic modular body (50) which snapped fixed on the bearing unit (20) and is radially limited by a radially outer, axial cylindrical surface (11) integral with the outer ring (21) and a radially inner, axial cylindrical surface (12) integral with the inner ring (22); coupling device (80) being provided to join mechanically the plastic body (50) to the bearing unit (20) so as peripheral edges (27, 28) partly define the relevant cylindrical surfaces (11, 12), and the plastic modular body (50) being provided, for each ring (21) (22), with two annular bodies (62, 64) (71, 73) which are mounted on either side of said central flange (21f, 22f).
