摘要:
A radial shaft seal for sealing a closed inner chamber (K), filled with a fluid medium (M), on a rotating shaft (W) that is guided out of the inner chamber (K) through a receiving opening (2), relative to an external atmosphere (A), has two membrane bodies (3, 4), each having a sealing membrane (5) having a sealing lip (6) positioned obliquely to the inner chamber (K), where the two sealing lips (6) can be positioned on the shaft (W) in sealing fashion at an axial distance from each other, and a supporting device (7) for supporting the membrane bodies (3, 4) resting thereon. To improve the service life and reduce the internal pressures, it is proposed that the two membrane bodies (3, 4) be positioned at a distance from each other over their entire course, and that the supporting device (7) includes a supporting body (8) located between the membrane bodies (3, 4).
