ABSTRACT:
An improved seal (10) for use in a universal joint (11) having an elastic seal ring (23) compressed between a pair of right circularly cylindrical sleeves (24,25). The seal ring is bonded to the sleeves. The sleeves are adapted to have press-fitted relationship with association portions of the universal joint, such as the journal trunnion (12) and the bearing retainer (14). In one form, the elongated extent of the sleeves is parallel to the axis (15) of the journal trunnion (12) and in a modified form, the sleeves (124,125) extend perpendicularly thereto. In each form, a portion of one of the sleeves is disposed adjacent the inner end of the needle bearings (22,122) so as to limit axial movement thereof. The sleeves are bonded to the seal ring so as to preclude sliding movement therebetween while yet permitting limited axial play in the universal joint thereby to provide long troublefree life of the seal.
