Abstract

A sealing arrangement used to create a seal between a first part of a chain and a second part of the chain, wherein the second part can at least be pivoted in relation to the first part, includes a sealing ring with an annular sealing lip for sealing a lubricant area between parts which can be pivoted towards each other, and an elastic ring which is adapted to be fixed to one of the parts and which is adapted to exert pressure in the sealing ring. In addition, a supporting ring is arranged between the sealing ring and the elastic ring.
