The super high rollers retain all the excellent functions of UHMWPE. The wear resistance is 7 times that of steel, and it is 3 times that of nylon. It has anti-friction self-lubricating, impact resistance, noise and vibration elimination, anti-adhesion and anti-corrosion. , anti-aging and so on. In the past two years since its launch on the market, the ultra-high engineering plastic idlers have been tested for long-term use and have been well received by customers. They are widely used in metallurgical mines, coal mines, chemical industry, grain storage, building materials, ports, salt fields, and electric power. It is the best alternative to metal roller. The promotion and application of ultra-high engineering plastics UHMW-PE idlers has brought about obvious economic benefits in comparison with the traditional metal conveyor idlers in terms of improving transportation capacity, protecting belts, reducing repairs, and saving energy and reducing consumption.
- Abrasion resistance and long life
The shell is made from UHMWPE which has abrasion resistance 10 times that of HDPE and 7 times that of steel. UHMWPE roller have been subjected to continuous abrasion in very extreme quarrying, coastal and industrial applications.
- Impact resistance and Impact energy absorbing
UHMWPE has the highest impact strength of any engineering plastics, about three times which of nylon, two times that of PC, five times that of ABS, withstands repeated impact, even at -196 it is tough, together with its superior abrasion and corrosion resistance. UHMWPE has made itself ideally suited for industrial applications in complicate and rough environments.
- Effective sealing system
The primary labyrinth seal prevents most of the dust to get into the bearing house, and no water could leak in. The narrow
clearance between bearing house and shaft forms the second sealing, the bearing house are made of UHMWPE which has a
very low surface energy and are anti-adhesion, so it is repulsive to dust and water. It is quite difficulty for dust to get through the
- Light weight and energy saving
UHMWPE rollers are only one third less in weight than steel roller, they are even lighter than HDPE roller, since they have superior strength .Light weight and low friction result in considerable energy saving.
- Reduced belt damage
UHMWPE shell is self-lubricant, and prevent the adhesion of any transfer material, so no damage was caused to conveyor belt, even in case of roller be stopped.
- Provision of steel drums, each bucket is directly connected to the chain through specially designed chain plates.
- Drive sprocket can be provided in segmented rim structure - for easy replacement.
- The tail sleeve has a pair of high-chromium bushing bearings - completely enclosed within the housing - eliminating the possibility of dust leaking to the outside atmosphere.
- Provide safety switches, such as zero speed switch, start level indicator and electronic vibration relay.
