A sealing ring which, when viewed in cross section, is formed in the shape of a 7, has a first axial leg and a sealing leg that has a sealing lip, the sealing leg being connected to a first end face of the axial leg by means of a joint, and has a clamping element for stabilizing the sealing leg in the radial direction. The clamping element is annular and, when viewed in cross section, is formed by a 7-shaped spring, and has a second axial leg and a stabilizing leg, the second axial leg being connected to the first axial leg and the stabilizing leg being connected to the sealing leg.

Sealing ring and the use thereof

A wiper for the sealing arrangement of a cylinder arrangement having a cylinder and a piston rod, having a support lip facing in the direction of the space that is to be sealed off, and a wiper lip facing towards the surroundings, as well as a holding element from which the support lip and the wiper lip protrude, wherein the free end of the wiper lip is bent in the direction of the piston rod.

Wiper

A sealing ring with a dynamically loaded sealing lip having a sealing edge and a tension element for stabilizing the sealing lip in the radial direction, wherein: the tension element is arranged in a mounting groove; the mounting groove is arranged in the sealing lip on the side facing radially away from the sealing edge and has a mounting opening on the side facing radially away from the sealing edge, which opening is delimited by two guide webs arranged so as to be adjacent to each other at a spacing in the axial direction; the sealing lip is articulated, on its side facing axially away from the sealing edge, to a support member with a joint; and the sealing lip and the support member delimit, with their sides which radially face each other, a substantially C-shaped joint space which is open on one side in the axial direction.
