Abstract: A bearing unit comprises a radially outer stationary race (1) and a pair of radially inner rotatable half-races (2a, 2b). An intermediate annular chamber (8) is defined between the outer race (1) and the inner half-races. The intermediate chamber communicates with the outside through first air passages (5) formed in the outer race and with the inside of the bearing unit through second radial air passages (6) defined between the inner half-races. The second passages (6) are defined by an intermediate annular member (10) which is axially interposed between the inner half-races (2a, 2b) and forms one or more blade surfaces (12a, 12b) extending from the second passage (6) to the intermediate chamber (8) for capturing air from the intermediate chamber and conveying it into the second passage.

Abstract: A hollow suspension standard (20) of a vehicle equipped with a system for supplying pressurized air to a tire through the hub of the wheel has an inner cavity (22) and a seat (21) for housing a wheel hub bearing unit (10). The standard (20) forms a first passage (23) for establishing fluid communication between the inner cavity (22) and the hub-bearing unit (10), and a second passage (24) establishing fluid communication between the inner cavity (22) and a source of pressurized air mounted on board of the vehicle.

Abstract: A bearing unit comprises an outer stationary race (1) with a first inner passage (6) for the air, and two axially adjacent inner half-races (2a, 2b) rotatable with the hub of a wheel. Formed between the inner half-races are essentially radial second inner air passages (7, 71, 72). These passages have surfaces (71d, 72d) inclined forwardly with respect to a direction of rotation (A, B) so as to favor the air flow through the rotating part of the bearing.

Abstract: Sealing device (1) with a sensor for a rolling bearing (2), in which the sealing shield (7) is mounted between two races of the rolling bearing (2), and a encoder wheel (8) is arranged inside the rolling bearing (2) between the two races and the shield (7); a detecting (9) sensor being arranged inside a housing (10) which is obtained through the shield (7) and which is also arranged with a respective detecting surface which directly faces the encoder wheel (8).

Abstract: Bearing/hub group (1) with a sensor (8) for vehicle wheels, the group (1) presenting at least one rolling race which can revolve around a rotation axis A: a fixed rolling race (4) which is arranged outside the revolving rolling race (3) in a position which is coaxial to the revolving rolling race (3) itself and which is provided with a support flange (7) which projects towards the outside; and a sensor (8) which is mounted on the fixed revolving race (4) being made of different materials, and being connected to each other by an interface element (9) which is integral with the flange (7), and by two axial blocking elements (10) which are integral with the fixed rolling race (4) and which abut the interface element (9).

Abstract: Static sealing element (1) for a rolling bearing (2) which is mounted on a cylindrical element (3) which presents a blocking moulding (4) which is positioned against an inner race (5) of the rolling bearing (2) itself and which is suitable for being arranged in contact with a shoulder (6) the sealing element (1) presenting a support (8) which is associated with the inner race (5) of the rolling bearing (2), and a sealing lip (9), which forms an integral part of the support (8) and which presents, in turn, a substantially conical end portion (17), which axially projects in relation to the blocking moulding (4) and which radially forks opposite the blocking moulding (4) itself.

Abstract: A suspension standard (10) for a motor vehicle has a cylindrical seat (11) for accommodating the outer, non-rotating race (13) of a wheel hub bearing (12). At least one body (16; 16′, 16″; 22) distinct from the standard (10) and the outer bearing race (13) has end portions (16a, 16b) extending in a radially outer direction on opposite sides (10a, 10b) of the standard so as to axially lock the bearing with respect to the standard.
