Abstract

1. A rod or piston seal comprising a sealing ring (1) arranged in an installation space and having a circumferential recess, which sealing ring (1) has a sealing lip (4) projecting axially in the direction of the sealed medium and having a sealing edge (5) bearing against the relatively mobile machine part and is composed of polymeric material, as well as a pressure ring (2) made of resilient elastic material and arranged in the recess, which pressure ring (2) has a cross-section fitted to the profile of the recess and is less hard than the sealing ring (1), the recess of the sealing ring (1) being open radially in the direction of the installation space over its entire axial extent, and the pressure ring (2) having its largest radial extent prior to installation in the radial plane of the sealing edge (5), characterised in that the sealing ring (1) is composed of polyurethane, in that the sealing lip (4) in the radial plane of the sealing edge (5) has an extent in the radial direction which is 0.2 to 0.3 times as large as the radial extent of the installation space, in that the rod seal is fixed in the recess in axial direction by projections (7) of the pressure ring (2) distributed evenly in circumferential direction, and that free spaces are provided radially outside and inside as well as between the projections, into which free spaces the material of the pressure ring (2) is able to spread during the elastic deformation caused by the installation.
