Abstract (en)
A roller assembly primarily intended for chain conveyors comprising a roller (26) journalled for rotation on a bushing (36), the roller being sealed against ingress of foreign matter by at least one labyrith seal, said seal comprising a pair of overlapping rings (46,56) received in a counterbore (42) in one end face of the roller, one ring (46) being fitted to the bushing and the other (56) to the roller, whereby passage of grease through the seal is restricted to a tortuous path formed by said overlapping rings. <??>In use, the inner ring (46) provides an axial thrust bearing surface (101) for the roller. The rings are preferably L-shaped in cross-section and are suitable for use with rollers of metal or plastics material.
