Adopted high-carbon steel with precision stamping and strengthened by heat treatment, it features high hardness, excellent elasticity, and resistance to deformation and fracture.

The thickness tolerance is precisely controlled within ±0.01mm, with a smooth and burr-free surface, ensuring an accurate fit of gearbox clearances.

It is suitable for the range gear assembly of Sinotruk HW series gearboxes. With good wear and corrosion resistance, it maintains stable clearances during long-term operation, reduces transmission noise and wear, improves gear shifting smoothness and transmission efficiency, and extends the overhaul cycle of the gearbox.
