Free roller



contact us 021-69790948 Miss Li. Can be customized according to customer product types and requirements. If you need more detailed free roller / unpowered roller product information, solutions and quotations, please contact online customer service, we will provide you with warm service.

The unpowered roller is a cylindrical component that manually drives the conveyor belt or changes its running direction. It is one of the rollers and the main accessory of the conveyor equipment. The main function of the unpowered roller is to transfer the goods by manually pushing the goods. The unpowered drum consists of the following and parts:
(1) Cylinder: generally made of round tube. Commonly used are steel pipes and plastic pipes, and high precision and high strength can be made of round steel;
(2) Inner shaft: Generally made of round steel. Small diameter can be cold drawn round steel, large diameter can be turned with high accuracy;
(3) end cap: generally made of carbon steel. Small diameters with small loading capacity can be processed by punching, large diameters or large loading capacity can be processed by turning;
(4) Bearing: Select the appropriate standard bearing according to the cylinder and the end cover.

Free rollers are made according to the material of the outer tube, the diameter of the tube, the diameter of the shaft center, the material of the shaft center, the thickness of the wall, and the calculation method of the size. Generally, there are two types. One is the end cap made of yellow PP material. There is also a free roller of the non-powered internal axis shaft type conveyor, and a free roller of the non-powered internal axis shaft type conveyor with an end cover made of metal as a material.
