Abstract
A contoured double-lip seal and bearing assembly incorporating at least one such seal in the annular gap between the annular races thereof. The double-lip seal comprises a reinforcing washer in which a mass of fluid resistant resilient material is secured and is integrally formed with a pair of annular axially spaced sealing members. The inner sealing member adapted to be disposed adjacent to the anti-friction elements of the bearing is of an arcuate transverse configuration and terminates in a sealing lip of a frusto-conical configuration which projects axially and radially outwardly of the bearing at an acute angle to the axis of the bearing and is disposed in resilient sliding sealing relationship on a cylindrical section of one of the race members. The outer sealing member also terminates in an outer sealing lip of a frusto-conical configuration projecting axially and radially in the same direction as the inner sealing lip and projects at an acute angle to the surface of a chamfer formed on the outer end portion of the one race member.
