The invention relates to a combination of a sealing set with a pin, e.g. that of a universal-joint spider, with a preliminary seal composed of metal or plastic and a main seal composed of rubber or a similar flexible material, the preliminary seal resting with undersize on a pin region adjacent to the rolling-element track, and the smallest diameter of that part (19) of the preliminary seal (13) which rests on the pin (12) being up to 2% smaller than the diameter (D) of the rolling-element track (15) of the pin (12) and corresponding essentially to that part of the pin contour adjacent to the rolling-element track (15) and consisting of a recess (16) and, if required, transitional surface (17). <IMAGE> |
