Premium Bend Pulley Nondriving Pulley China Factory and Suppliers
The Bend Pulley (Non-driving Pulley) is a critical component designed for precise belt guidance and tensioning within heavy-duty conveyor systems. Engineered to withstand rigorous industrial environments, these pulleys ensure smooth belt transitions and optimal alignment, significantly reducing friction and premature wear on the conveyor belt. Available in light, medium, and heavy-duty configurations, they provide versatile solutions for diverse load requirements across multiple industrial sectors.
Our bend pulleys are manufactured using high-grade carbon steel and precision-engineered bearings to ensure operational stability and an extended service life exceeding 30,000 hours. With customizable lagging options including polyurethane, ceramic, and diamond rubber, these pulleys offer superior grip and durability, making them indispensable for high-capacity transport systems in mining, metallurgy, and chemical processing plants.

Frequently Asked Questions
The difference lies in the bearing bore size and connection method. Light-duty (80-100mm) uses single keys, while heavy-duty (200-220mm) employs telescopic sleeves and cast-welded steel plates for extreme load support.
For mining and high-abrasion environments, ceramic rubber or diamond rubber lagging is recommended as they provide superior grip and wear resistance compared to smooth or flat rubber surfaces.
Yes, our bend pulleys are manufactured in strict accordance with GB, ISO, DIN, CEMA, and JIS standards to ensure compatibility with global conveyor systems.
G40 balancing minimizes centrifugal force and vibration during rotation, which prevents premature bearing failure and reduces the mechanical stress on the entire conveyor structure.
We use premium double-row aligning cylindrical bearings from world-leading brands such as SKF, FAG, NSK, NTN, and TIMKEN to ensure smooth rotation and self-alignment.
Absolutely. We offer customization for outer diameters (219mm-2000mm) and lengths (500mm-6000mm) to fit your specific conveyor layout and belt width.
