High-quality motorcycle chain, selected quality standard carbon steel 40Mn, the chain plate stamping bright belt reaches more than 90% and pitch accuracy is controlled within 0.03mm by our latest moulds, to ensure assembly accuracy and link firmness, improve wear resistance and avoid distortion of the finished chain .

The bush is made of 20Mn material with better wear resistance. The roundness tolerance is less than 0.02mm through precision curling equipment to improve the wear resistance. and tempering at medium temperature to reduces the internal stress and improves the toughness, so it has excellent shock resistance performance. 

The pin adopts tungsten steel cutting die, the end face is flat and the length error is within 0.1mm, and then processed by centerless grinding to make the upper and lower roundness uniform, reduce friction to the greatest extent, and chamfer roundness between R0.4-0.5 , Effectively guide the assembly without damaging the chain plate.

The automatic mesh conveyor belt furnace has stable temperature and uniform heating with aeration, which greatly improves the dispersion of the carburized layer depth and surface hardness of the chain parts to ensure the overall quality stability and wear resistance of the chain to achieve extension. The service life of the chain.

Electroplated nickel color, anti-corrosion and attractive,  not easy to fade and dull.
