Abstract
A secondary sealing device is for a wheel bearing assembly including a fixed inner axle with an outer circumferential surface and a bearing inner race, an outer hub rotatable about the inner axle and having an inner circumferential surface and a bearing outer race, rolling elements disposed between the inner and outer races, and a primary seal(s) connected with the inner axle and sealingly engaged with the outer hub. The secondary sealing device includes a rigid annular body having an inner radial end coupled with the inner axle and an outer radial end spaced radially inwardly from the inner circumferential surface of the outer hub so as to define an annular gap between the body and the outer ring. The body is located between the primary seal and an axial end of the hub so as to provide a barrier configured to prevent contaminants from contacting the primary seal.
