The axial sealing lip extends at an angle of ≧35° in relation to a symmetry axis of the shaft seal, when the axial sealing lip has not been installed yet and is under no tension, and extends from the sealing edge of the radial sealing lip at a length of ≧1.4 mm. When the shaft seal is installed, the axial sealing lip rests against the contact surface at an axial overlap of 0.05 to 0.55 mm.
