Lip-type shaft seal

A lip-type shaft seal for sealingly separating pressure compartments, in particular for sealing two components movable relative to one another, comprising:

• a seal body defining a symmetry axis and made of elastic material which has a Shore A hardness of ≦75, said seal body having a first radial sealing lip for placement in a pocket and terminating in a second axial sealing lip, said radial sealing lip having a sealing edge and bearing against a rotating component, which extends in a direction of the symmetry axis, said axial sealing lip having a sealing edge which, in installed state, rests against a contact surface oriented radially to the symmetry axis;
• a spring element for urging the sealing edge of the radial sealing lip against the rotating component;
• and
• a reinforcing element integrated in a radial sealing portion of the seal body so as to be embraced by one side of the sealing portion,
• wherein the axial sealing lip extends at an angle of ≧35° in relation to the symmetry axis, when the axial sealing lip has not been installed yet and is under no tension,
• wherein the axial sealing lip extends from the sealing edge of the radial sealing lip at a length of ≧1.4 mm, when the axial sealing lip has not been installed yet,
• wherein the axial sealing lip rests against the contact surface at an axial overlap of 0.05 to 0.55 mm, when being installed.
