ABSTRACT:
The seal includes a substantially rigid annular base member and a generally C-shaped unitary body of elastomeric material having an inner section overlying and bonded to the outer surface of the base section, a pivot section extending outwardly from the outer surface of one end portion of the base section, and an outer section mounted by the pivot section for movement toward and away from the other end portion of the base section. During use of the seal its connector section and part of its outer section are under bending stress, and engaged portions of the outer and inner sections are both under compression stress. The outer section is biased outwardly toward the periphery of the bore of a grease-containing housing by the combined tendency of each of the foregoing body sections to return an unstressed condition. A segment of the inner section of the elastomer body projects beyond one end of the base member and, during use of the seal, has radially bulging portions in lateral engagement with the compressed portion of upper body section and with the aforesaid end of the base member.
