Product Description

Our high elastic PU round belts are made of 100% cast polyurethane (PU), offering superior elasticity, wear resistance and dimensional stability. Designed for continuous conveying and power transmission, they easily flex in any direction, making them ideal for multi-pulley, spiral and complex conveyor layouts.

Why Choose Our PU Round Belts?

• Excellent elasticity & rebound – keeps tension under fluctuating loads, reduces slip and maintains stable drive performance.
• Wide temperature range – performs reliably from approximately -20°C to +80°C (short-term up to +100°C).
• Oil & abrasion resistant – withstands oils, greases and most industrial chemicals, extending belt life.
• Low noise & smooth operation – vibration-dampening surface protects products and bearings.
• Easy endless joining – simply cut to length and weld the ends with a hot butt-welding gun; the joint reaches near-original strength.
• Multiple diameters & colours – round profiles in popular diameters, colour-coded by hardness for easy identification.
