ABSTRACT:
Proposed is a sealing arrangement for shafts with very small diameters, with an essentially U-shaped lip seal (6) subjected to the force of an axially acting helical compression spring (9). The two sealing lips (6.1 and 6.2) of the lip seal (6) are by thrust parts (8) with working surfaces (8.1) of wedge-shaped arrangement spread apart in such a way that the radially inner sealing lip (6.1) is pressed tightly on the shaft outside circumference and the radially outer sealing lip (6.2), independently thereof, tightly on a housing wall (5).
