Abstract
A seal, especially for dishwashers, for sealing a shaft. The seal comprises a bellows made of elastic material, with a support housing and a slide ring associated therewith. The bellows at least partially overlaps the slide ring and the support housing. An inner side of the outer wall of the bellows engages an axially parallel peripheral wall of the support housing. The seal also comprises a pressure spring which operates between the support housing and the slide ring. The peripheral wall of the support housing, and the inner side of the outer wall of the bellows, have such a profiling that support surfaces are arranged on the peripheral wall transverse to the force of the pressure spring, and that corresponding countersurfaces are arranged on the outer wall, the support surfaces and countersurfaces being arranged in axial sequence. The profiling of the peripheral wall of the support housing and the outer wall of the bellows is preferably step-like or serrated, and extends transverse to the axial direction of the seal.
