<p>The seal has a sealing lip (1) that is pressed against a surface (4) to be sealed of a machine element (5) in a radial direction (3) by an annular power transmission element (2). The power transmission element includes an effective diameter (7) that is varied on sides in the radial direction with an aid of an adjusting mechanism (6), where the effective diameter is adjusted infinitely variably. The power transmission element has a circular cross-section, and a hose (9) of elastic material, where the adjusting mechanism is arranged in the hose of the elastic material.</p> |
