cnc machined conveyor UHMW PE polyethylene uhmwpe plastic parts roller
Roller is an important part of the belt conveyor, it accounts for 35% of the total cost of a belt conveyor, bear more than 70% of the resistance. Roller's role is to support the conveyor belt and the weight of the material. Roller must be flexible and reliable operation, reduce the friction with roller conveyor belt, to take up of the total cost of more than 25% of the conveyor belt conveyor life plays a key role. Therefore, the quality of the roller is particularly important.
Ultra-high molecular weight polyethylene (UHMWPE) the supporting roller is a new generation of plastic instead of steel of high-tech products, by the ultra-high molecular weight polyethylene pipe material, plastic, metal, bearings, metal shaft bearing and seal assembly and become a hi-tech product. I company specializing in the production of ultra-high molecular polyethylene belt conveyor roller is the main raw material ultra-high molecular weight polyethylene, and according to the change of the roller surface material, the manufacturing structure also made corresponding change, make its abrasion resistance, rotational coefficient is greatly improved, such as to make it compared with the metal roller or ceramic roller, has many obvious advantages in the use of performance, is China's best-selling ultra-high molecular polyethylene roller.
