Conveyor Corrosion-Resistant Upe Pipe Roller

HDPE conveyor roller for corrosive duty

The Anyang Ultrahigh roller tube is extruded from pure ultra-high molecular weight polyethylene with a molecular weight above 3.5 million. The material gives the roller self-lubricating behaviour, abrasion resistance and ageing resistance without any surface coating.

Bearings are supplied by established manufacturers such as HRB, LYC, SKF and NSK to secure the service life. The seal is injection moulded from high strength material so that the bearing survives dust, moisture and wash-down duty.

Because the shell does not corrode and does not build up sticky material, these rollers are widely used on belt conveyors in coal, cement, steel, power, chemical and coking plants, where they replace steel rollers directly.

Advantages over steel rollers

• Long service life – more than five times the life of a steel roller.
• Belt protection – the polymer tube surface is smooth, non-magnetic and does not pick up iron powder, dust or sticky material. Its low friction coefficient against the belt extends belt life by around 20%.
• Light weight – roughly one third of a steel roller and one fifth of a ceramic roller, which simplifies installation and saves power.
• Labyrinth sealing – the seal design protects the bearing and needs no maintenance after installation.
• Low noise – about half the noise level of a steel roller.
• Corrosion resistance – suitable for acid, alkali, salt and other chemically aggressive conditions.
• Cost performance – a slightly higher purchase price than steel, recovered several times over during service life.
• Vibration damping – the material absorbs shock, protecting the bearing and extending its life.
• Safer operation – avoids the belt tearing and friction heating that occur when a steel roller shell fails or seizes.
