Sealing ring and sealing arrangement, including two such sealing rings

摘要

A sealing ring for sealing a machine element includes a stiffening ring of a hard material, a supporting ring having a radial flange positioned adjacent a radial surface of the machine element and a sealing sleeve of an elastomer material connected to the stiffening ring. The sealing sleeve includes a sealing lip for sealing against the radial surface of the machine element so as to create a sealed-off space. The sealing sleeve also incldes an outer axial leg and a radial leg connecting the sealing lip to the outer axial leg. The outer axial leg includes a first end proximate to the sealed-off space and the sealing sleeve is connected to the stiffening ring at the first end. In addition, a sealing arrangement including two such sealing rings.
