Product Introduction:

Ultra high molecular polyethylene nylon roller is a new product developed by our company in recent years. It has many obvious advantages over the traditional steel, ceramic and rubber roller in performance. It retains all the excellent properties of UHMWPE nylon, with self-lubrication, impact resistance, noise and vibration elimination, anti-bonding, anti-corrosion,Uhmw Pe anti-aging and so on. Compared with traditional metal rollers, the popularization and use of ultra high molecular polyethylene nylon roller has very significant economic benefits in improving transportation capacity, protecting belts, reducing maintenance, saving energy and reducing consumption.

Performance Introduction:

1. Sealing performance

Roller adopts contact labyrinth seal, combined 

with the superior performance of contact seal and the advantages of small rotation resistance of labyrinth seal, dust-proof, waterproof, grease impermeable, long-term maintenance of its physical performance, stable speed, no bearing stuck phenomenon, reduce the running resistance of the conveyor.

2. Silencing performance

The new roller adopts a new noise reduction technology. The external bearing is equipped with a porous bearing sleeve to meet the required deflection requirements. Instead of a large-clearance bearing, the porous bearing sleeve plays a role of shock absorption and noise reduction, which will not affect the downhole personnel dialogue under normal operation. Ultra high molecular weight polyethylene nylon has impact absorption and damping, can effectively eliminate noise and vibration, so as to protect the bearing from impact damage and greatly extend the overall service life of the roller. The noise produced by the steel roller is significantly reduced, greatly improving the working environment of underground workers.

3. Self-lubricating and non-bonding

The roller has non-adhesive surface, no rust, self-lubricating, so it has better protection for the belt, on the other hand, it will not produce the phenomenon of "bite" belt, even when the roller does not rotate, it will not damage the belt.

4. Corrosion and wear resistance

Ultra high molecular polyethylene nylon roller is a kind of saturated molecular structure, so its chemical stability is very high, this product can resist the erosion of strong chemical substances, in addition to some strong acid at high temperature has slight corrosion, in other lye, acid solution is not corroded, can be used in the concentration of less than 85% concentrated hydrochloric acid, The performance is quite stable in sulfuric acid (less than 80%) and nitric acid (less than 20%), so the corrosion problem of the roller can be completely ignored in complex underground coal mine operation. The roller has high corrosion resistance and wear resistance. Compared with the steel roller, the service life of the roller is longer than that of the metal roller.

The wear resistance of roller rod skin is 7 times that of steel and 3 times that of nylon, and it is impact resistant and not easy to damage, which greatly extends the life of the belt.

5. Light weight

Ultra high molecular polyethylene nylon roller light weight, easy to install, greatly reduce the labor intensity of workers, save maintenance costs
