Abstract

A chain comprises inner link plates that are each connected to an adjacent outer link plate by means of at least one pin that passes through overlapping portions of the respective links. Outboard of the inner link plates the pin supports a rotary bush with a radially extending flange. The bush in turn supports one end of an outer link plate and a roller. The outer link plate is an interference fit with the bush and the roller is rotatable relative thereto. In use the rollers are supported on a guide rail as the chain moves. The location of the bush bearing and roller provides easy access for maintenance and lubrication.
