Belt Conveyor Spiral Polyurethane Idler Roller for coal mining industry

Product Introduction

Spiral idler roller is a new generation roller product developed by our company, which is composed of roller cover, bearing, seal assembly and shaft. The unique sealing technology of this product completely isolated the contact between the bearing and the outside world to prevent the bearing from contamination. Each roller is made of superior materials to ensure the quality of the products.

Product Components

1.The spiral idler roller tube is extruded with pure ultrahigh molecular weight polyethylene material, with a molecular weight of over 3.5 million and excellent performance of self-lubrication, wear resistance and aging resistance. 

2.The bearings are made by HRB, LYC, SKF, NSK and other well-known domestic and overseas bearing manufacturers to ensure the service life.

3.The sealing parts are made of high-strength materials by injection molding and can withstand various severe working conditions.

Spiral idler roller can prolong the equipment service life, save energy source and improve working environment effectively. It has been widely used in the transport system of coal, cement, steel, electric power, chemical, coking and other industries. It is an ideal replacement product for steel roller of belt transport machinery. 

Product Advantages

1. The rubber belt is made into left and right rubber threads on the same axis. When the idler rotates, it produces centripetal cohesion under the action of the helix, and the self-set center would not deviate.  

2, Spiral roller structure and process is simple, bearing directly installed in the steel pipe,which results in strong rigidity.
