Abstract

In this bush conveyor chain, the cylindrical lubricating surface (12) between the bush (20) and the roller (10) is continued on each side by a lateral lubricating surface (13). This is bounded by an end face of the roller and by an upper leg of a cover (14) pressed firmly on the bush. The cylindrical leg (14b) of the cover (14) projects into a groove (15) manufactured on the roller. A projection on the bush receives an elastic sealing ring (16) under prestress, the elastic sealing ring (16) having a lip bearing elastically against the cover. By means of this arrangement, the escape of oil is prevented. What is obtained is virtually a combination of sliding lubrication and labyrinth lubrication. <IMAGE>
