ABSTRACT:
A sealing ring for sealing about a relatively-movable shaft has a sealing surface and resilient means for resiliently bearing the sealing surface on the shaft. At least one annular projection projects from the sealing surface for contacting the shaft. The annular projection is made recessional into the sealing surface, by making at least the portion of the sealing ring at the sealing surface of a rubber having a Shore A hardness of from about 65 to about 90, in such a way as to leave a portion of the sealing surface in contact with the shaft at an annular surface region spaced axially from the annular projection.
