Abstract
A sealing assembly includes a sealing element and its placement in homokinetic joints. This sealing element seals the outer joint part relative to a pipe or a hollow shaft. The sealing element is connected with the outer joint part which is connected with a sealing rolled bellows on the opposite side. In this case, the sealing element is configured as a closure lid provided with a pressed projection, and a set back piece on its outer circumference. This lid includes a cylindrical or turned over shape, and is disposed on the outer joint part of the homokinetic joint by way of the pressed projection and by secondary weld seams of a friction weld or magnetic arc weld that connects the outer joint part with a pipe. This connection is with a shape fit or a force fit whereby the closure lid in the set back partial piece is configured with a circumferential groove as well as with planned breakage points.
