Abstract: 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.
