Abstract
A cassette seal comprising a U-ring having legs projecting in the direction of a rotating machine part, a counterring connected to the rotating machine part, and at least one sealing lip fabricated from an elastomer material which rests under pretension against the running surface of the counterring extending in the axial direction thereby forming a seal. The counterring has the shape of a hollow cylinder and is free of unrelieved internal stresses. The counterring is associated with the legs of the U-ring with a small axial clearance on both sides whereby the counterring and the U-shaped ring enclose a hollow space having substantially rectangular boundaries. The sealing lip is mounted on the U-ring and extends into the hollow space formed by the counterring and the U-shaped ring.
