Abstract
In the illustrated embodiments, an elastomer body has a relatively thin metal layer overlying the elastomer surface to be loaded so as to prevent adhesion at the elastomer surface in spite of a long period of dwell in contact with a relatively more rigid cooperating part such as a hard rubber stop. In a basic form, a thin metal sleeve may encircle a cylindrical elastomer body. The outer surface of the sleeve may be grooved for extra adhesion resistance. In a further development, the sleeve is formed as a helical wire spring which may be confined between two flanges integral with the elastomer body.
