Abstract:
1. An idler roller for supporting an endless belt in an open roller conveyor, said idler roller including: a frame for mounting the idler roller to the conveyor; a support shaft mountable to the frame for supporting the idler roller; and a roller casing having a free end and a mounted end, the roller casing rotatably mountable to the shaft at said mounted end by a bearing assembly, the bearing assembly being positioned proximate the mounted end and substantially enclosed within the roller casing, wherein the idler roller is cantilevered to the conveyor such that the bearing assembly is able to be designed to be positioned within the roller casing so that the load from a material on the conveyor corresponds to the approximate position of the bearing assembly, minimising the bending moment from the load on the bearing assembly wherein the idler roller extends from the frame upwardly such that the bearing assembly is at a lower elevation relative to the free end.
