This kind of Polyurethane roller is very soft and supper low noise. Durometer has 75-95 Shore A. Polyurethane has better abrasion and tear resistance than rubbers, while offering higher load bearing capacity. Compared to plastics, urethanes offer superior impact resistance, while offering excellent wear properties and elastic memory. Urethanes have replaced metals in sleeve bearings, wear plates, sprockets, rollers and various other parts, with benefits such as weight reduction, noise abatement and wear improvements being realized. The wheel outer covered with PU, Polyurethane (commonly abbreviated PU) is a unique material that offers the elasticity of rubber combined with the toughness and durability of metal. It allows the engineer to replace rubber, plastic and metal with the ultimate in abrasion resistance and physical properties.

Large size of polyurethane rollers are usually used for Fitness Equipment, Vending Machine Wheels, Aluminium Extruded Sections, Printing Machine, Packing Machine and Transmission belt, etc.

Small size of polyurethane rollers are usually used for Sorting Machine, bill counter, money counter and currency sorter.
