Abstract
A shaft seal in which a sealing lip provided on an elastomeric portion of a first annular member is in sealing contact with a sealing surface of a second annular member which in operation is adapted to rotate relative to the first annular member, and in which an annular elastomeric support portion provided on the first annular member supports axial forces on a radial surface of the second annular portion. The support portion includes protrusions with apices which cooperate with the radial surface of the second annular member and are distributed circumferentially at uniform intervals.
