ABSTRACT:
A seal assembly includes a stiff annular case and a resilient annular seal. The seal has a peripheral rim connected to a peripheral edge of the case and a peripheral rim extending radially from the case for resiliently radially sealing against a first surface, such as a shaft or shaft housing, spaced radially from the case. An intermediate rim extends axially from the body of the seal relative to the seal and case for resiliently axially sealing against a second surface, such as the outside surface of an antifriction bearing, located axially adjacent the case and extending between the first surface and the case. The peripheral edge of the case to which the seal is connected may be skewed at an obtuse angle relative to a radial flange of the case. The seal extends radially outward from the case in one embodiment and radially inward from the case in another embodiment.
