Product Details

Ultra high molecular polyethylene roller (UHMW-PE Roller) is an advanced product which is to substitute stainless roller, which has some disadvantages such as heavy, easy to be eroded, easy to stick with transporting material, high static electricity and others. it includes ultrahigh molecular polyethylene pipe which is produced by high technology as its body, bearing seat and seal are fully rubber material made by one-time. Then, they are sealed with three layers of water-proof and dust-proof installation via labyrinth and contact method.

Characteristics

Good lubricity and not bonding, so no bonding and piling up material on the surface of the idler. Guarantee the steady operation of the belt conveyor.

Friction coefficient is much lower than steel, reduce the friction between the idler and belt, that reduces the driving force of the belt conveyor.

Long working life, is 3~5 times of the steel.

Because of the good performance of the UHMW-PE, also extending the working life of the belt conveyor.

Light weight which is 1/3~1/2 of the steel weight, conveniently installing and changing, reducing the maintenance and labor intensity and also reducing the 25% electricity.

Effectively reducing the operation noise, UHMW-PE has better shock absorbing performance and damping performance.

Good load bearing performance and anti-corrosive performance, it can be meet the heavy load of the belt conveyor according to adjusting the thickness.

Adapt to large scope of the working temperature. ( can work from -40℃ ~ 80℃).

Application

Ultra High Molecular Roller is the substitution product of stainless roller; it is also equipped in the belt conveyor, which is widely used in coal mines, metallurgy, ports, construction site, power station, and chemical, especially in food and medicine industries.
