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.

A seal assembly for sealing a cavity formed between radially-spaced, coaxially disposed, relatively-rotatable inner and outer members having an antifriction device coaxially disposed between the inner and outer members; the antifriction device having radially spaced, coaxially-disposed, relatively-rotatable inner and outer rings spaced apart by antifriction elements, the inner and outer rings having end faces at each axial end of the antifriction device; the seal assembly comprising: a stiff case of endless annular shape comprising a radial flange having a peripheral edge and a skewed flange having a peripheral edge, the skewed flange being connected to and forming an obtuse angle with the radial flange, the radial flange being connectable between a protuberance located juxtaposed a respective axially adjacent ring end face of the antifriction device and extending from one of the outer member and the inner member, the protuberance axially restraining the antifriction device so that the radial flange is axially supported by the axially adjacent ring end face and held between the protuberance and the axially adjacent ring end face with the skewed flange extending axially away from the antifriction device and radially away from the radial flange; and a resilient seal of endless annular shape, the annular seal including: an outer peripheral rim and an inner peripheral rim, one peripheral rim being sealingly connected to the skewed flange in such a manner that at least an annular portion of the radial flange axially coincident with the axially adjacent ring end face and contiguous with the peripheral edge of the radial flange is not resiliently covered by the resilient seal, the other peripheral rim extending radially from the case for resiliently radially sealing against a first surface spaced radially from the case; and an intermediate rim extending axially relative to the seal and the case for resiliently axially sealing against an end face of the one of the inner and outer ring which is not axially supporting the radial flange.
