Polycord Belt

Polycord belt with polyester core

Polycord belt with polyester reinforcement is a multi-layer power transmission belt designed for high-precision applications requiring stable tensile performance. The outer layer is made of thermoplastic polyurethane with a hardness between 90 and 95 Shore A, offering excellent resistance to abrasion, tearing, and chemical exposure. A reinforced polyester core is embedded within the belt to absorb tensile loads and minimize long-term elongation. Standard diameters typically range from 5 to 15 millimeters, with tensile strength measured between 70 and 100 megapascals. These belts operate reliably within a temperature range of -15 to +80 degrees Celsius and support accurate thermal welding for seamless joining.

The polyester core in the polycord belt improves performance in systems with frequent starts and stops by preventing undesired longitudinal stretch. Required initial tension during installation is typically lower than non-reinforced belts, defined between 3% and 5%. This reduces bearing loads and extends the service life of mechanical components. Polycord belts with polyester reinforcement are ideal for packaging machinery, robotics, precision automation systems, and conveyors with sensitive positioning requirements. The maximum permissible linear speed is up to 30 meters

Round polycord belt

The round polycord belt is made of thermoplastic polyurethane with a circular cross-section, designed for power transmission in light to medium-duty systems. The belt diameter typically ranges from 2 to 20 millimeters, with a surface hardness between 85 and 95 Shore A. Its tensile strength lies between 40 and 60 megapascals, and the operating temperature range is from -20 to +80 degrees Celsius. These belts offer good resistance to abrasion, light oils, and mild chemicals. Due to their thermoplastic structure, they can be thermally welded, simplifying installation.

The round polycord belt is designed for high flexibility and quiet operation, making it ideal for sensitive industrial applications and confined spaces. The recommended initial tension during installation is typically 5 to 8 percent of the belt length to prevent slippage and efficiency loss. The maximum linear speed these belts can handle is up to 25 meters per second. With high fatigue resistance, they provide long service life in repetitive applications. These belts are optimized for light conveyor systems, packaging machinery, and industrial automation equipment.
