The idler is an innovation in the technical field of parts and components of transportation equipment. Mining roller is efficient, cost effective and deliver more benefits. Welcome to choose us! Notes: Its main structure is composed of roller body, roller shaft, roller skin, idler mechanism, bearing seat and bearing. The basic structure and external size of idler are not changed.The reverse check mechanism adopts new technology, the reverse check mechanism can only rotate in the forward direction, the reverse check mechanism will be stuck by the shaft during the reverse operation, can not rotate, the conveyor belt can only slide a short distance on the reverse idler, effectively prevent the reverse of the conveyor belt, reduce the hazard of broken belt, improve the safety coefficient of the conveyor. Hebei hengguang conveyor machinery manufacturing co., LTD. Specializes in the production of various specifications of idlers, can be customized to the drawing, short construction period, excellent quality, fair price, welcome to contact us.
