Abstract text

A wheel bearing assembly for motorcycles comprising a hub, a bearing, a bearing seal, a collar, and an axle. A sealing element such as an o-ring, rubber seal or sleeve is provided between the inside surface of the collar and the axle, in a substantially watertight static relationship therewith, so as to prevent moisture from seeping between the collar and the axle disposed therein. The sealing element is preferably retained in a groove machined into the interior surface of the collar, but may be frictionally retained thereby or in a press fit relationship therewith.
