ABSTRACT:
A sealing device for a universal joint comprising an annular cup surrounding each branch of a spider element of the universal joint and fixed with a bearing ring capping the end of the associated branch. A flexible sealing element having lips on the periphery thereof is engaged with an inner circular flange of the annular cup. According to the invention, the annular cup comprises a cylindrical skirt mounted to bear against a flange of the corresponding branch of the spider element, the skirt extending in a direction substantially perpendicular to the circular flange of the annular cup. This arrangement reduces the interference between the annular cup and the flexible sealing element, which is composed of rubber, to thereby increase the effectiveness of the seal afforded by the device.
