Abstract
A seal assembly is for sealing a space between an inner surface of an outer member and an outer surface of a shaft within the outer member. The seal assembly includes an annular seal body having first and second axial ends, inner and outer circumferential surfaces, and a seal lip extending radially inwardly from the body and having an inner surface sealingly engageable with the shaft surface. The seal body is sized such that a clearance space is defined between the seal body outer surface and the outer member inner surface and a portion of the body inner surface is engageable with the shaft such that the body is radially displaceable within the clearance space when the shaft displaces radially. A retainer coupled with the outer member has a radial surface and a biasing member biases the seal body toward the retainer radial surface or a radial stop surface.
