UHMWPE UHMW-PE roller / polymer plastic roller roller UPE
UHMWPE by the roller is a high molecular weight polyethylene pipe and metal bearings, metal shaft, plastic end caps, bearings, seals and other assembled a product.
main advantages:
1., light weight, one-third the weight of steel roller.
2. easy installation, no maintenance, saving raw materials
3. wear resistance, and increased roller life, energy, chemical resistant (not damage the belt), low noise.
widely used on retractable leather belt, including the roller and the roller under the two categories. Aaaaa dust is mainly used for larger, corrosive place, replace coal, mining , coking , food processing, salt, sugar, cement, minerals, metallurgy, chemical industry, port and other industries in the roller belt conveyor .
the company can customize all kinds of rollers. Proposed power price! | UHMWPE idler rollers and steel contrast |
