Abstract
A sealing ring wherein both the first and the second sealing lip are well protected from mechanical damage/destruction. The relatively more sensitive first sealing lip is particularly well protected and, in particular, is protected from exposure to service life-reducing contaminants. Furthermore, the production of the sealing lip is simple and economical.

A sealing ring comprising:
- a supporting ring connected with a first sealing lip made of an elastomeric material and a second sealing lip made of a polymeric material, said second sealing lip being wedged against the supporting ring by a clamping plate without being bound to it;
- said clamping plate for purposes of precentered installation of a machine element that is to be sealed into the sealing lip, the clamping plate being provided with an insertion slant that projects axially in a direction opposite to that of an installation direction of the machine element and of the first sealing lip, and having a diameter that increases in funnel-like fashion axially in the direction opposite to the installation direction and to the first sealing lip;
- and
- the second sealing lip acts as a second centering ring for further precentered installation of the machine element and being located after the first centering ring in the installation direction, and acting as preliminary seal for the first sealing lip.
