ABSTRACT:
In a wheel bearing assembly, a roller bearing is mounted within the hub of a wheel, with the outer race of the bearing being fitted in a hub of the wheel. A sealing ring is fitted in the hub. The sealing ring has an angular cross-section, with an axially extending portion engaging the bore of the hub, and a radially inwardly extending portion extending along the outer race. A fastening device, such as a cam surface, is provided on the axially extending portion of the sealing ring to enable fastening of a cap to the assembly. A portion of the radially inwardly extending portion of the sealing ring is axially displaced away from the outer race, so that the surface thereof away from the bearing may serve as a sealing surface engaging a further seal in use of the device.
