Roller pulley

transportlight-duty

Using international standard design and manufacturing technology, the corporation can produce head pulley, tail pulley and bend pulley. Driving pulley is the main part for transmitting the power. As per the different carrying capacities, The driving pulley can be divided into three categories: light duty, medium duty and heavy duty. And for the same diameter of the pulley, there are many different axle diameters and central spans. Light-duty: Bearing Aperture: 80~100mm. The axle and the hub are connected by the single key. And it’s single plate welding. The axle is unidirectional out. Medium-duty: Bearing Aperture: 120~180mm. The axle and the hub are connected by the ring lock. Heavy-duty: Bearing Aperture:: 200~220mm. The axle and the hub are connected by the ring lock. The shell body is aluminothermic welding fabric. The axle can be unidirectional and two-way out. The surface treatment of the driving pulley can be smooth steel, herringbone or rhombic rubber lagging. The smooth steel pulley is available for the place which environment is small power, small belt width and dry. The herringbone rubber lagging has a big friction factor, better anti-slippery and drainage ability, but it has its own direction. The rhombic rubber lagging is available for two-way operating conveyors. The vulcanized rubber lagged pulley are mostly used for important applications The bearing housing of the pulley is lubricated by grease cup style lubrication
