    • The rolling-contact bearing comprises one outer race 11, two inner races 12,13, two rows of rolling bodies 14 held in cages 15 and a built-in device for detecting the speed of rotation, of the type comprising a sensor means 17 and an encoder means 19 which are located in the annular chamber defined between the inner races 12, 13 and outer race 11 and the rolling bodies 14. The encoder means 19 comprises an active part 20 capable of creating in the sensor means 17 a periodic signal of frequency proportional to the rotational speed of the bearing 1. The encoder means 19 comprises a support part 21 secured to the inner races 12,13 and made of a nonmagnetic material, so that the said support part 21 axially holds the inner races 12,13 against each other before the bearing 1 is mounted in the mechanical assembly for which it is intended.According to the invention, the encoder axially secures the inner races after the bearing has been assembled and cannot come into contact with the rolling bodies.

    • A composite annular encoder (15) for a bearing with information sensor (16), comprises an annular metal support (21) of L-shaped cross section with a plane radial part (21a) and an axial part (21b), and a annular element (22) produced as a single piece made from thermoplastic material, which annular element is constituted by a radial part (22a) which includes the multipole ring (22b) and is overmolded onto the plane radial part (21a) of the metal support, and by an axial retaining part (22c) overmolded onto the outer surface of the axial part (21b) of the metal support. The metal support has, on its axial part, anchoring points (21c, 21d) for the overmolding of the axial retaining part (22c) of the annular element made from thermoplastic material, enabling the thermoplastic annular element and the metal support to be rendered axially and circumferentially integral.

    • Rolling-contact bearing equipped with a sealing device for the passage of a fluid. The bearing comprises a rotating race and a non-rotating race, through each one of which there pass channels (6,7) for the passage of fluid, rolling bodies (3) between the rotating race and non-rotating race, and a sealing device (8) mounted between the rotating race and non-rotating race to form a sealed intermediate chamber (14) communicating with the channels (6,7) for the passage of the fluid. The intermediate chamber has two flexible walls (11), the free end parts of which form two sealing lips (12) in rubbing contact with a bearing surface (13) of one of the races (2) of the bearing. The sealing device (8) comprises two coaxial seals made of a flexible material and held against each other by means of a metal reinforcing member (10), each of the seals comprising a ring of axial teeth (16) separated from one another by circumferential gaps. The dimensions of the teeth and of the gaps separating them are such that when the two seals of the device are held against each other, the teeth of one of the seals of the device penetrate between the teeth of the other seal of the device forming radial channels (23) for the flow of fluid through the device.
