Our belts are manufactured using high-strength chloroprene rubber or hydrogenated nitrile rubber (HNBR) bonded with multi-layer Kevlar fiber cords. They deliver exceptional resistance to high temperatures, oils, and ozone, with tensile strength enhanced by over 30%. This ensures outstanding transmission efficiency and longevity even under extreme operating conditions ranging from -30°C to +130°C. The product undergoes rigorous bench testing including dynamic fatigue, thermal cycling, and salt spray corrosion. Precise Matching OEM pulleys and tensioners minimize slippage and noise, ensuring long-term stable operation of the engine timing system and accessory systems.
Precision-molded tooth profiles reinforced with Kevlar cord enhance meshing accuracy by 20%, maintaining zero slip even at high speeds with transmission efficiency ≥98%.
HNBR rubber layer + aramid fiber composite maintains flexibility within the temperature range of -40°C to +150°C, offering crack resistance, ozone resistance, and resistance to oil and grease corrosion.
The optimized back-side flocking noise-reduction layer and rounded pulley crown reduce belt-pulley engagement impact noise by 3-5 dB, delivering a quieter ride.
Factory-grade length, width, and pitch tolerances. Compatible with mainstream Car models. No modification required—direct replacement. Easy to install.
