Abstract
A sealing ring having a sealing body with a dynamically stressed sealing lip made of an elastomeric material which at least partially surrounds a toroidal supporting body. The supporting body has a slope facing the sealing lip, and the sealing body has a dynamically stressed sealing bulge which is adjacent with an axial distance on the side of the sealing lip facing away from the space to be sealed. The sealing bulge is in contact with the face to be sealed under an initial elastic stress. The sealing bulge is arranged axially between two radial planes which axially delimit the slope.
