Using Japan imported high-quality synthetic HNBR rubber(or CR rubber) as the main raw material, with a variety of different uses of auxiliary materials; The skeleton material is high quality glass fiber cord imported from Japan. The tooth surface is protected by nylon 66 high elastic cloth and made in strict accordance with technical specifications. It has the characteristics of clean appearance, full tooth shape, long service life and low noise.
Features
● Good aging resistance: Especially excellent ozone resistance.
● Good chemical stability: In addition to strong oxidizing acid, resistance to general chemical erosion
● Excellent oil resistance: Has extremely low oil swelling resistance, better oil resistance.
● Durability is good: The dynamic performance is better than CR synchronous belt,it is the first choice of high-grade car transmission belt.
● Excellent wear resistance: Wear less than neoprene synchronous belt, reduce noise, effectively prolong the service life of the timing belt

About Timing Belt Drive
The specific requirements of timing belt drive for modern automotive: Durability increased by more than 1.5 times; Bandwidth reduction of 20%; Heat resistance increased by 10℃. Timing belt is composed of rubber, fiber tensile body (glass fiber or aramid fiber) and nylon tooth cloth composite. Both fatigue life and water resistance of HNBR timing belts are much better than those made of CR rubber and chlorosulfonated polyethylene.
