Patent ID: 8721186

Claim:
A bearing assembly comprising: a radially outer stationary bearing race defining a first side surface thereof, an inner cylindrical surface and an outer cylindrical surface; a radially inner bearing race having an outer cylindrical surface facing the inner cylindrical surface of the radially outer stationary bearing race and defining a gap therebetween; a magnetic encoder including an annular disc fixed onto the outer cylindrical surface of the radially inner bearing race, the annular disc being located in the gap and having a radial thickness greater than an axial thickness and a radially extending face facing out of the gap; and a protective cover of non-ferromagnetic material mounted on the radially outer stationary bearing race and abutting against the first side surface, configured to protect the magnetic encoder and to close the gap and presenting a radial peripheral portion abutting against the first side surface extending to an axial cylindrical edge abutting the outer cylindrical surface and further extending to a radially inwardly projecting portion extending inwardly to cover a side of the radially outer stationary bearing race being opposite from the first side surface of the radially outer stationary bearing race and further abutting the radially inner bearing race wherein the magnetic encoder extends radially substantially from the outer cylindrical surface of the radially inner bearing race to proximal the inner cylindrical surface of the radially outer stationary bearing race.
