Abstract

A dynamic seal for sealing radially two members that are displaceable relative to each other axially comprises a sealing body made of elastomeric material having two axially spaced, radially exterior sealing lips and two axially spaced, radially interior sealing lips, and a supporting body bearing the sealing body and consisting of a harder material than the sealing body, in particular of a plastic. The supporting body possesses a radially exposed guiding portion extending between two sealing lips in the axial direction for axially guiding the movable member, and an anchoring portion opposing the guiding portion for anchoring the seal in the other member.
