ABSTRACT:
A dynamic seal assembly is intended for use as a facial seal between radially inner and outer relatively rotating members having a seal body mounted on a generally L-shaped annular ring, a counterface mounted on the inner of the relatively rotating members with the bearing disposed in journaled relation to the counterface, and the seal body having a sealing lip disposed at an acute angle with respect to the seal body to engage a radial flange on the bearing member and a flexible diaphragm extends radially and outwardly from the seal body to terminate in an outer circumferential sealing portion in sealed engagement with the outer of the relatively rotating members. The bearing member is so disposed with respect to the counterface as to maintain a uniform circumferential band of contact between the sealing lip and flange portion of the counterface notwithstanding axial or radial shifting between the relatively rotating members.
