Abstract:
A sealing ring comprising:a toroidal supporting body having a longitudinal axis, and a sloped portion set at an angle with respect to the axis, the sloped portion of the supporting body being bound by two radial planes which define the axial extent of the sloped portion; a sealing body comprising a dynamically stressed sealing lip, the sealing body being made of an elastomeric material which at least partially encloses the supporting body, wherein the sloped portion of the supporting body is in contact with the sealing body such that the surface of the sloped portion of the supporting body that is in contact with the sealing body faces in a direction towards the sealing lip, and the sealing body having a dynamically stressed sealing bulge on the side of the sealing lip facing away from a space to be sealed, said sealing bulge coming in tight contact with the surface to be sealed under an initial elastic stress, wherein the sealing bulge is arranged between the two radial planes in the axial direction.
