Polyurethane Idler Rollers

Polyurethane idler rollers are industrial parts made of polyurethane. They usually install in belt conveyors, chain conveyors and other drive systems. Although idler rollers don’t provide power drive, they support and guide belts or chains to run smoothly. They help belts maintain the right running track, prevent belt misalignment, and ensure smooth and efficient material conveyance.

Feature of Polyurethane Idler Rollers

Polyurethane idler rollers possess high elasticity. They can cushion the impact force generated during the belt's running, effectively reducing the vibration and noise during equipment operation.

Meanwhile, these rollers feature good abrasion resistance, oil resistance, and chemical corrosion resistance. They can operate stably in harsh industrial settings, endure the friction between the belt and the idler roller surface, extend the equipment's service life, and cut down maintenance costs.

Polyurethane Coated Idler Rollers Structure

Polyurethane coated idler rollers can be designed in either a solid or hollow structure. Compared to solid idler rollers, hollow idler rollers are lighter in weight and have a smaller rotational inertia. This characteristic enables them to reduce the driving power required by the motor, thereby achieving energy savings. As a result, they are particularly suitable for conveying light materials or in applications where energy conservation is a high priority.
