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.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 applicationsThe bearing housing of the pulley is lubricated by grease cup style lubrication.
