A B S T R A C T An idler roller consists of a roller body which comprises a plastic core having a bore to accommodate an idler shaft and a shell of polyurethane located around the core to provide a tubular load-bearing wall. Bearing assemblies are located within the roller body at each end thereof for receiving the idler shaft. A channel-shaped metallic insert is embedded in the shell, the insert spiralling around the whole length of the core. An electrically conductive clip or the like connects the metallic insert to a bearing assembly to drain any electrostatic charge formed on the surface of the polyurethane shell away from the shell via the bearing assembly to the idler shaft.
