Belt conveyor pulley is the main component of belt conveyor, could be divided into driving pulley and driven pulley according to different usage. The surface could be smooth painted, or covered by rubber.
Driving pulley provides the driving force for the conveyor. In order to increase pulley life and traction, it often has a larger diameter than other pulleys.
Driven pulley is also called as redirection pulley, which is used to redirect the conveyor belt or press it tightly.
The Head Pulley gives motion to the conveyor belt. The driving pulley can be at the head end or at the tail end, depending on the layout of the conveyor, space available and loading conditions. It is the head end where generally the belt discharges the carried material and return for loading. Besides, we offer these Head Pulleys at the affordable price range.
Product Description
1, This series Drive rollers are welded by steel plate, and using rolling bearings.
2, The surface of drive plulley includes three type: smooth, plastic and cast plastic. Usually the smooth pulley can be used on condition that the power is not big, and the the ambient temperature is low. The plastic surface pulley should be used when it is easy to slip.
The quality of cast plastic pulley is better.Becasue the external surface layer is wear-resistant. The packed plastic drum can achieve the same performance. It's easy to replace rubber surface , easy to maintain.And it's also be considerde affordable and durable.
3, Please refer to the following table for each bandwidth of the roller.
4, The diameter selection of entire core plastic conveyor belt drive pulley is same as the same intensity rubber conveyor belt.

Our Pulley Feature:
1. The belt conveyor drum/ pulley is made by large seamless steel.
2. Use flame cutting machine to precisely cut tube.
3. Weld the pulley inner disc with professional welding machine.
4. Weld the shaft sleeve and disc with the positioner.
5. Process the outside circle with large drum lathe to guarantee the even wall thickness.
6. We select #45 round steel and sleeve to ensure the concentricity and reduction for the eccentric shaft force.
7. Equip the inner bearing enlargement device to avoid bearing damage from beating.
8. We will make the static balance inspection when the belt speed exceeds 2.5m/s.
9. We can produce different type,different standard pulley according to customers’ request.
