The pulley directly was made by large seamless steel. We precisely cut the tube by using the flame cutting machine, and weld the inner pulley disc by using the professional pulley welding machine, and weld the pulley sleeve & disc by using the positioner. We use the large drum lathe process the outside circle, so that it ensures the pulley has the uniform thickness and small pulsation. We chose 45# round steel & sleeve and process the whole shaft so that it ensures shaft concentricity and reduction for the eccentric shaft force. It make sure the pulley move more stable, high quality bearing which is hot charging and bearing block are equipped inner bearing enlargement device, so the bearing can be easily pushed to the bearing position and it avoids the bearing damage from the beating. We need make the eliminating inner stress treatments when the pulley’s withstand forces exceed 80KN and we will make the static balance inspection when the belt speed exceeds 2.5m/s.
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.
