UHMWPE conveyor belt roller has a novel structure, reliability seal, and advanced material selection. Rollers and housing are made of ultra-High Molecular Weight Polyethylene (UHMWPE) which has anti-friction self-lubrication, impact resistance, anti-adhesion, and anti-corrosion, resistant to aging, and other characteristics. Compared with existing nylon, HDPE, phenolic, ceramics, iron roller, wear resistance, lightweight, non-sticking materials, no damaged belt, seismic shock absorption, energy, and other advantages. UHMWPE conveyor belt roller 7 times more wear-resistance than steel, 4 times than nylon.
