Abstract
A sealing arrangement in which a rotary shaft lip seal is arranged in a housing bore hole under radial prestressing. The lip seal has a sealing lip sealingly surrounding a shaft to be sealed. The sealing lip is arranged on a first, radially inwardly pointing leg of a thrust ring made of tough material. An axially extending second leg of the thrust ring is provided with a coating of elastomer contiguous with the sealing lip on its radial exterior that is also under radial prestress when positioned against the wall delimiting the housing bore hole. A roller bearing is arranged in the radial direction between the second leg and the shaft, and the sealing lip is arranged in the axial direction on the side of the roller bearing and the first leg facing the space to be sealed. The second leg is at least partially enclosed by the coating on an end face facing away in the axial direction and, together with the coating, can be positioned against a longitudinal limit stop provided by the bore wall in a vibrationally isolated manner.
