Roller Chain

1. Pin surface Cr-v altogether permeability, enhance the wear resistance
2. Use German import of raw material, stable performance, high life.Surface is bright and clean, smooth, high dimensional accuracy and mechanical performance is good
3. Introduce Japanese precision mold, precision punch of Japan,chain plate with high precision.Introduce Germany pin machine and roll machine, the size precision
4. Pin and plate isothermal treatment, enhance the fatigue performance
