Abstract

A sealing arrangement for sealing off a rod capable of lateral movement from a housing which surrounds the rod with radial clearance is disclosed. The sealing arrangement comprises a sealing ring of a polymer material, which is provided with a radially movable sealing lip and is accommodated in a sealing housing. An auxiliary sealing lip is provided, with which the housing is able to be brought into engagement by the force of a compression spring which is active in the axial direction. The sealing ring is braced by means of a guide ring against the rod, and the auxiliary sealing lip forms a one-piece component of the sealing ring.
