A wheel bearing is provided with a sealing device comprising in-cluding at least an outer structure and an inner structure together de-limiting a chicane passage having an inlet. The outer structure forms an annular gutter which is open radially outwards. The inlet of the chicane passage and the shrink-fitting portion of the outer structure are situated axially on either side of the gutter. The shrink-fitting portion of the outer structure is situated on one side of a reference plane of the outer ring, perpendicular to the axis of revolution and tangential to the end wall of the outer ring opposite to the chicane passage and to the gutter.

Wheel bearing equipped with a sealing device with gutter and chicane

A bearing includes an inner ring, an outer ring and a sealing device. The sealing device includes at least an outer structure secured to the outer ring, and an inner structure secured to the inner ring. The inner structure includes a shrink-fitting portion shrink-fitted onto a shrink-fitting bearing surface of the inner ring and at least one seal seat. The outer structure includes at least one seal lip in sliding contact against the seal seat. The seal seat is located axially at a distance from an end wall of the inner ring, and is closer to the axis of revolution than the shrink-fitting portion.

A motor vehicle drive wheel assembly comprising a fixed subassembly comprising two outer raceways; and, a rotating subassembly comprising a first inner race, a second inner race and two rows of balls arranged in two pitch planes PPand PP. The second inner bearing race has an outer diameter, measured in a section plane perpendicular to the axis of rotation and located between the first pitch plane and the second pitch plane, at a measurement distance DM of the first pitch plane, which is greater than a given threshold value VS.
