Abstract

See full text

An edge-welded bellows, including a plurality of diaphragms and a guide part for guiding on the outer surface of a rod extending through an inner through-opening of the bellows or for guiding on the inner surface of a tube surrounding the bellows. The guide part has a retaining fin, which, at the edge thereof, lies between the edges of adjacent diaphragms and is welded thereto, and a guide sleeve, which surrounds the longitudinal central axis and has a guide surface for guiding the bellows on the outer surface of the rod or the inner surface of the tube. The guide sleeve has a wall thickness that is more than three times that of the retaining fin. The guide sleeve has a step having a contact surface. The retaining fin lies, in a region adjoining the edge thereof, on the contact surface and is form-fittingly secured against being lifted off from the contact surface.
