ABSTRACT:
A sealing arrangement for sealing a shaft passing through a bore in a wall is disclosed. The sealing arrangement comprises a radial shaft sealing ring which surrounds the shaft with radial pre-tension, forming a seal on the circumference of the shaft via at least one sealing lip made of an elastomeric material. The sealing lip is affixed on a first shank of an essentially L-shaped first reinforcement ring which faces radially inward. A second shank extends in an axial direction, is mantled by elastomeric material at least in the portion which extends axially, and touches the wall with radial pre-tension, forming a seal. In the radial direction, between the shaft and the second shank, is arranged a rolling bearing, which contacts the shaft via its inner ring and contacts the mantled partial region of the second shank via its outside ring.
