The Timing Belt is a toothed meshing transmission belt. It is integrally molded with high-strength fiberglass or aramid cord cores and wear-resistant rubber, ensuring non-slip transmission with a constant ratio, high precision, and an efficiency of up to 98%. It features low noise, tensile resistance, oil and heat resistance, and requires no lubrication. The belt runs smoothly with shock absorption and vibration damping, greatly extending the service life of bearings and equipment.
l Accurate & Slip-Free Transmission
Toothed meshing drive ensures precise and stable speed ratio with high positioning accuracy.
l High Strength & Tensile Resistance
Made of high-quality rubber and strong cord cores, it is tensile, wear-resistant, and resistant to breakage and deformation.
l Low Noise & Smooth Operation
Low running impact, excellent vibration damping, and quieter operation.
l Oil & Heat Resistant, Long Service Life
Anti-aging, oil and high temperature resistant, adapting to various harsh working conditions.
l Lubrication-Free & Easy Maintenance
No lubrication required, simple installation, and lower long-term operating costs.

Maintenance Tips：
l Do not forcibly bend or twist the belt during installation to avoid damage to the internal cord cores.
l Check the tension regularly; excessive slack may cause tooth skipping, while excessive tightness will accelerate wear.
l Avoid prolonged contact between the belt and corrosive substances such as engine oil, acids and alkalis.
l Replace the belt in a timely manner if tooth wear, cracking or rubber peeling is found.
l Keep the pulleys clean to prevent foreign objects from getting stuck and causing abnormal wear.
