Abstract:
A mechanical seal, comprising:a housing; a slide ring rotatably fixed with respect to the housing, the slide ring having a sealing surface; a counter-ring having a sealing surface, the slide ring and the counter-ring being axially preloaded against one another so that their respective sealing surfaces are in sealing contact with one another in a manner allowing relative rotation therebetween; an axially extending high-grade metal bellows having two end faces, one of which is sealingly connected to the housing in a non-adherent manner, and the other of which is sealingly connected to the slide ring in a nonadherent manner; a first polymeric bearing ring for connecting the slide ring to the bellows, wherein the bearing ring at least partially surrounds the slide ring; and a clamping ring surrounding the first bearing ring with a radial clearance defining a gap sufficient to permit the first end face of the bellows to be forced into the gap formed by the clearance.
