ABSTRACT:
A shaft seal has an annular housing with a first and a second flange and of a hollow, frustrated cone seal ring, the apex of which is anchored liquid-tight for rotation with axial displaceably but on the shaft. The large end of the conical sealing ring forms a sealing lip which bears elastically on the inner face of the second flange which is directed toward the medium to be sealed, having essentially the shape of the frustum of a hollow. The first flange forms an annular support surface (2) which bears on the seal ring (2) between the apex shaft gripping end and the sealing lip so that the shape of the seal ring is elastically deformed.
