ABSTRACT:
An improved grease-expelling wheel bearing assembly (1) comprises a grease expelling seal (3), and a grease distributor (5). The grease distributor (5) comprises a collar (7) for mounting about the shaft (9) of a rotor nut (11) and, projecting from the collar (7), at least one grease spreading blade (13) extending radially outwards from the collar towards the assembly housing (15), part (17) of the area between the collar (7) and the housing (15) not being covered by a blade (13), the arrangement being such that rotation of the blade (13) causes grease expelled from the bearing seal (3) to be spread evenly around the circumference of the seal, without preventing its contact with the rotor nut (11).
