The idlers are very important component of belt conveyor. They are present along the entire length of the conveyor, supporting the belt and moving the materials loaded on the belt. The idler’s diameter could be correctly selected to comply with the belt width and travel speed. The correct idler length could be selected according to belt width and rollers type. General steel idlers consist of idler shell, spindle, bearing, bearing house, seals and axial fixed units.
