ABSTRACT:
A sealing device comprises a slide ring having a sliding surface and a counterring affixed to a shaft, the sliding surface of the slide ring sealingly contacting the counterring and capable of rotating relative to the counterring, the slide ring, on a side facing away from the sliding surface, being sealed relative to a retaining ring by a sealing element of elastomeric material, the retaining ring being biased by a compression spring away from a housing which has an essentially C-shaped cross-section open in the direction of the slide ring. The sealing element is constructed as a ring-shaped bellows and has an essentially N-shaped cross-section with a first radial segment and a second radial segment which are connected by an axial segment. The first radial segment sealingly contacts an end face of the slide ring facing away from the sliding surface, and the second radial segment sealingly contacts an inner segment of the housing.
