The sealing device (8) for the passage of a fluid between a rotating race and a non-rotating race of a bearing each penetrated by channels (6, 7) for the passage of the fluid, comprises a one-piece annular central body (9) of elastic material having a circular shoulder (10) for fixing to one of the races (1), and two main sealing lips (12) which mutually form an annular intermediate chamber (13) and which are in friction contact with the other race (2). The central body (9) is penetrated by at least one channel (15) communicating with the channels (6) of the race associated with the circular fixing shoulder, and also with the intermediate chamber, which communicates with the channels (7) of the other race, so that the fluid introduced into the channels of one of the races of the bearing passes through the central body in a leaktight manner and exits through the channels of the other race.

The rolling-contact bearing comprises a rotating race and a non-rotating race through each of which there pass ducts (6, 7) for passage of fluid, rolling elements (3) between the rotating and non-rotating races, and a sealing device (8) fitted between the rotating and non-rotating races in order to form a leaktight intermediate chamber (14) communicating with the ducts (6, 7) for the passage of fluid. The intermediate chamber has two flexible walls (11) of which the free end parts form two sealing lips (12) in frictional contact with a contact surface (13) of one of the races (2) of the bearing. The frictional contact surfaces (13) are inclined with respect to the axis (XX') of rotation of the bearing. The flexible walls (11) extend substantially parallel to the contact surfaces so that the contact pressure between the sealing lips and the surfaces varies in the same direction as the pressure of the fluid in the intermediate chamber (14) of the sealing device.

A device for sensing the rotation speed of a bearing comprises an encoder member fastened to a rotating part of the bearing and a sensor assembly comprising a plastics material sensor support housing a sensor and a metal support for locating and fastening the sensor assembly on and to a non-rotating part of the bearing. The sensor support is overmolded onto the latter's outside surface. The sensor faces the encoder member in order to measure its rotation speed. The-metal support comprises a substantially axial centring portion adapted to cooperate removably with a bearing surface on the non-rotating part of the bearing and a washer-like plane radial portion adjacent the centring portion adapted to be clamped between a radial surface of the non-rotating part of the bearing and a radial surface of a non-rotating member. The device may be fitted to vehicle wheel hub assemblies.
