Ultra High Polymer Idler – Anti-Corrosion · Wear-Resistant · Ultra-Light
Engineered for the Harshest Industrial Environments
🛠 Product Overview
The Ultra High Polymer Idler is designed for extreme working conditions where corrosion, abrasion, and contamination are constant threats. Made from Ultra High Molecular Weight Polyethylene (UHMW-PE) or other advanced engineering plastics, this idler delivers exceptional wear resistance, self-lubrication, and non-stick performance, making it ideal for coal mines, fertilizer factories, salt plants, chemical industries, and port terminals.
Unlike steel or traditional HDPE rollers, these idlers offer superior impact resistance, are extremely lightweight, and operate silently—reducing energy consumption and extending the life of both the idler and the conveyor belt.
✅ Key Features
Ultra High Molecular Weight Polymer Shell for long-lasting abrasion resistance
Self-lubricating, non-stick surface that resists material build-up
Excellent corrosion and impact resistance – ideal for salt, chemical, and coastal applications
Significantly lighter than steel idlers, reducing overall conveyor load
Smooth and silent rotation with high-precision sealed bearings
Optional anti-static, UV-resistant, or flame-retardant versions
