The sealing lip is formed of acrylate rubber having different coefficients of thermal expansion. A portion (5,5',5'',5''') made of acrylate rubber with different coefficients of thermal expansion having a common boundary surface (6), is provided close to the sealing lip surrounding a ring having a circular cross-section. The portion and the sealing lip are firmly bonded to each other.</p> |
