The first screen includes a sleeve portion and a flange portion and also includes two sealing lips which cooperate with a sealing surface of the second screen. The first screen also has an annular projection extending from the sleeve portion that is adapted to be interposed, together with an extension of the elastomeric covering, between the front surface of the first ring of the bearing and a shoulder of the bearing itself. The second screen has a phonic wheel defined by a flange portion of the rigid reinforcement and a magnetized portion of the elastomeric covering. The elastomeric covering of the second screen has a front surface projecting beyond the front surface of the first ring.
