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.
Custom Manufacturing Capabilities
We utilize various polyurethane molding technologies and processing methods to manufacture polyurethane rollers in a wide range of shapes and sizes. This allows us to meet the diverse design requirements of different industries and equipment.
