<p>The present invention provides an idler roller (4, 5, 6) for supporting an endless belt (2) in a roller conveyor (1), said idler roller (4, 5, 6) including a frame (7) for mounting the idler roller (4, 5, 6) to the conveyor (1); a support shaft (8) mountable to the frame (7) for supporting the idler roller (4, 5, 6); and a roller casing (9) rotatably mountable to the shaft (8) by a bearing assembly (10), the bearing assembly being substantially enclosed within the roller casing, wherein the idler roller (4, 5, 6) is cantilevered to the conveyor (1) such that the bending moment of a load exerted on the roller casing (9) is displaced onto the bearing assembly (10). A roller conveyor (1) is also provided, which includes an endless belt (2) for transporting a bulk material (3) and a plurality of idler rollers for supporting the endless belt (2), wherein one or more of the idler rollers (4, 5, 6) are in accordance with the invention.</p> |
