A rolling element bearing for a wheel-support assembly of a vehicle, of the type having centring means (12) for a wheel (3) and its associated brake element (13) fixable for rotation with the outer ring (5) of the bearing (1); the centring means (12) are defined by respective cylindrical contact surfaces (27,28) of different diameter formed on the outer periphery of a sleeve (29) formed as an independent element interference-fitted in a frontal seat of the outer ring (5) to project therefrom, in such a way as to be fixed for rotation with the outer ring (5) against axial movement with respect thereto; preferably, the sleeve (29) has a seal element (33) cooperating with the inner ring (4) of the bearing (1) to provide a fluid and dust-tight seal for the protection of the rolling elements (6) of the bearing (1). <IMAGE> |
