Abstract:
A radial seal assembly comprising:an annular seal body having a channel disposed along an outside seal diameter and a channel base that defines the depth of the channel; a pair of legs that are spaced axially apart and that each extend radially away from the seal body, the legs defining axial surfaces of the seal body and axial sidewall surfaces of the channel; a sealing lip extending radially inwardly away from an inside seal body diameter, the sealing lip being integral with and made from the same material as the seal body and including an end portion that is adapted to form a seal against a rotary shaft surface; and an annular energizer disposed within the channel to provide a determined amount of radial seal movement within a seal housing disposed around the channel; wherein the annular energizer is in contact with both the seal and the seal housing to provide sealing surfaces between the seal and the seal housing when the seal is placed into sealing operation around the rotary shaft surface and a circumferential rib located on the seal housing being disposed at least in part in between the pair of legs.
