Precise hard chrome plating with uniform and firm coating. Excellent wear resistance, rust resistance and corrosion resistance against mud and oil, longer service life.
Optional QPQ treatment for higher surface hardness and lower friction. Great fatigue resistance, ideal for heavy-load shock absorbers.
CNC precision machining with strict tolerance control on outer diameter, roundness and straightness.
Perfect fit with oil seals and bushings, smooth movement, no oil leakage or abnormal noise.
Complete standard sizes. Custom length, diameter and end face processing available. Widely used for car, motorcycle shock absorbers and gas springs.
Smooth surface without burrs, low movement resistance. Ensure sensitive response and stable operation of shock absorbers.
