Round belt

endlessplainpolyester

Product description
Our PU round belts are manufactured from 100% cast polyurethane (PU) available in polyester- or polyether-based formulations. They provide high elasticity and excellent rebound, maintaining tension and minimizing slip in multi-pulley, spiral and complex conveyor configurations. Suitable for continuous conveying and light power transmission where flexibility and dimensional stability are required.

Key benefits

• High elasticity & rebound – maintains tension under variable loads and reduces drive slip.
• Wide operating temperature – continuous performance from -20°C to +80°C, short-term up to +100°C.
• Oil and abrasion resistance – resists oils, greases and many industrial chemicals to extend service life.
• Low noise & smooth operation – damping surface protects conveyed products and bearings.
• Easy endless joining – hot butt welding for cut-to-length belts produces joints with near-original strength.
• Multiple diameters & colour coding – round profiles in standard diameters, colours used for hardness identification.
