A sealing assembly is disposed so as to provide a sealing function between two parts of a track that are movable relative to each other. The sealing assembly includes an elastic ring having a radially-encircling sealing lip that fixedly and sealingly abuts on a first part of the track. The sealing assembly also includes a support ring that is rotatable relative to a sealing ring having a sealing edge. The support ring has a slip surface, on which the sealing edge sealingly abuts. |
