More Information
Summary: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.
