Abstract
A sealing element for sealing a shaft comprises a stiffening part, a first elastomer part connected to the stiffening part and adapted to adjoin the housing part and provide a static seal relative, and a second elastomer part of an elastomer material different from the elastomer material forming the first elastomer part. The second elastomer part is connected to the stiffening part and comprises a sealing section adapted to adjoin the shaft to seal a space. The sealing section comprises a return structure for returning a leaking fluid to a space to be sealed. The sealing section also comprises a region at one axial end portion of the sealing section which is peripherally closed in itself and extends along an inner surface of a circular cylinder portion of the sealing section that is adapted to adjoin and seal the shaft as the shaft is not turning.
