Sleeve chain (seamless sleeve)

1. Chromium vanadium co infiltration treatment: Cr-V co infiltration on the surface of the pin to enhance wear resistance. 2. Imported raw materials: German imported raw materials are used, with stable performance, high service life, smooth and flat surface, high dimensional accuracy and good mechanical properties. 3. Imported equipment manufacturing: Japanese precision punching machines and precision molds are introduced, with high chain plate accuracy and German pin and tube rolling machines, with precise and consistent part dimensions. 4. Isothermal treatment: Isothermal treatment of the chain plate to enhance fatigue performance. 5. Seamless sleeve: Seamless sleeve, formed by cold extrusion technology, with seamless cylinder and greatly improved roundness, not easily deformed. The seamless sleeve is matched with the pin shaft through surface contact rather than point contact, which increases the wear resistance of the product. 6. Smooth punching treatment of chain plate: independently developed
