Forged, the material flow line is complete, and the sprocket life is increased by 15% compared with the machine.

Once clamping to complete the inner hole, end face, end face arc processing, runout and roughness to reach precision gear blank accuracy.

Hobbing processing, accurate pitch, consistent tooth shape, small beating, accurate engagement, not easy to jump chain.

The use of unique cooling spray technology for high-frequency quenching treatment of the teeth, the depth of the hardened layer 1-2mm, the hardness of the entire tooth reaches HRC40-50, the hardened layer is uniform, no soft point, to avoid local transitional wear.

240-hour salt spray test without corrosion, greatly improving corrosion resistance.

With the use of the CHOHO chain, the transmission is more stable and the noise is less. Combined use can increase the service life of the chain sprocket by 50%.
