An annular seal of resilient material for creating a seal between a rotary shaft and a stationary member. The seal has an elongated mounting portion for embracing the surface of the shaft, an angularly extending intermediate portion which extends away from the mounting portion and stationary member, and an extremity portion extending angularly toward the stationary member with a sealing lip at its free end. A contact end surface is located at the end of the mounting portion on the end carrying the angularly extending intermediate portion. The sealing lip is in a first radial plane perpendicular to the center line of the mounting portion and the contact end surface being in a plane spaced from and parallel with the first plane in a static condition. By the above construction, the sealing lip will maintain a seal with the stationary member even at excessively high speeds of rotation. Also, because of the shape of the seal, it will be self-compensating as the result of wear thereof or axial movement of the shaft in a direction away from the seal.
