Abstract
The invention relates to a rolling bearing equipped with a sealing device having a frame fixed to a first organ. The first organ has a downstream sector bearing a sealing element and presenting a U-shaped geometry formed of an axial bottom surrounded with an inner wall and an outer wall at its edges. The outer wall is extended by a deflector that separates, with the U-shaped geometry, the sealing chamber into an inner compartment and an outer compartment. The bearing also includes a wall fixed to second organ, which presents an outside section forming with the deflector a reduced sealing clearance between the outside opening of the chamber and the outer compartment. The deflector has an outer surface placed in the outer compartment and is slanted towards the opening at an angle β from 10° to 80° relative to a radial direction.
