HDPE Roller Features


HDPE Roller Features


High-performance HDPE tube

A versatile substance with impressive tensile strength, the HDPE’s reinforced polymer matrix material makes a lightweight and durable roller.

Integrated sealing design

A non-metallic housing and three-tiered sealing system with a multi-labyrinth seal and contact seal means bearings are well protected from contaminants. Independent testing shows PROK HDPE's seal achieves 6x superior performance than other composite rollers on the market.

Visual wear indicator technology

Streamline conveyor roller maintenance with PROK's visual wear indicator technology. In a world first, PROK has introduced new visual wear indicator technology to the market which assists mining companies to improve maintenance planning. The Original PROK yellow tube combined with the green inner layer acts as a visual wear indicator for maintenance teams so they can better plan roller changeouts.

Friction welded bearing housing

PROK HDPE utilises friction welded bearing housings. The housing and tube are fused into one continuous material helping to transition stress and deflection. This feature eliminates the common failure mode relating to bearing housing dislodgement. The friction welded housing also creates an impenetrable seal preventing contaminants.
