Abstract
A sealing assembly for sealing a lubrication chamber defined at least in part by two pivotable track link portions is provided. The sealing assembly includes a sealing ring having an annular sealing edge sealingly abutting on an end surface of one of the portions and an elastic ring permanently abutting on the other of the portions and applying pressure to the sealing ring, the elastic ring having an axially-projecting, hollow cylinder-like sealing lip, which radially encloses the sealing ring in the region of a sealing edge and sealingly abuts on the end surface when two track link portions axially shift towards each other. A support ring is disposed between the sealing ring and the elastic ring.
