Features of hydraulic cylinder:
steady performance, high durability.

We use the cold drawn seamless steel tubes with strong honing technique. Length  of the cylinder can reach up to 3m with diameters from φ40-φ400. The piston rods are made of 40Cr with treatment of quality adjustment followed by high frequency quenching and then hard chrome plating, which makes it flexible inside and hard outside with high smooth surface. The piston rod's adopt quality NOK seals and diameters are from φ5-φ140. The quality of our cylinder is ensured by high-pressure test bed.
