HDPE plastic conveyor idler roll

HDPE polyethylene roller has physical and chemical properties which are high wear resistance, low friction coefficient,not easy to wear leather strap. It also has the fine self lubrication and not easy

to card to die in the bad conditions, antistatic, flame retardant, aging resistance, corrosion resistance.

It can withstand repeated impact, vibration, mechanical performance is excellent, light weight, easy

installation, no maintenance,low noise 93-7 DB), smooth operation.

The temperature of using keeps in -40°C to -80°C.

This product is widely used in the original dock transporting places where dust is bigger and the environment has high corrosive, such as mining, power, steel, Stone materials factory, cement and coking plant, coal washing factory, salt plant ,alkali plant, fertilizer factory, dock and so on.

(1)Low friction coefficient, waterproof, effective sealing system.

(2)High accurate steel pipes ensure the rollers with low vibration and noise.

(3)Multi-labyrinth seals achieve waterproof and dust proof.

(4)Adopt good bearing make sure the long lifetime, stable running and good quality.

(5)Stable running, good quality and attractive price.

HDPE Roller components

Packaging

The Testing.

the dust test

In this setup, the dust test is performed on our HDPE roller. After 200 hours nonstop running, there was absolutely no dust detected in the grease of the bearing.

the water test

During the water test, we let the SYHDPE roller run for 72 hours continuously while water

was sprayed on the sealing. After those 72 hours, there was absolutely no water in

the labyrinth sealing and the HDPE tube.

the rolling resistance

Also, the rolling resistance of the HDPE roller is measured. This is done at a speed of 600 rev / min with a radial load of 250 N. The measured rolling resistance was only 0.96 N.
