ABSTRACT:
A sealing arrangement includes a radial shaft seal and a sensor ring for inductively detecting angular motion relative to a sensor. The radial shaft seal has at least one dynamically stressed sealing lip of an elastomeric material that is affixed to a radially extending limb of an essentially L-shaped reinforcement ring. An axially extending limb of the reinforcement ring is joined to a statically stressed seal. The axial limb is surrounded at least radially on the outside by an extrusion coating of elastomeric material, the sensor ring having an axial projection that extends radially on the inner side and at least partially surrounding the extrusion coating with radial prestressing. The radial shaft seal and the sensor ring form one unit that is capable of being preassembled, so as to allow them to be separated from one another, as needed, without being damaged.
