Product Show

Our hydraulic cylinders are built for high performance and longevity:

• Piston rods are high-frequency hardened, reaching a hardness level of 55, and coated with hard chrome for superior strength.

• Forged rod ends, tube ends, and cylinder covers are automatically welded for seamless, high-strength connections.

• Tubes use premium 25Mn steel, undergo sandblasting, primer coating, and a two-layer top coat to resist wear and corrosion.

• Seals from Japan NOK and US SKF keep oil leakage below 1%, ensuring reliability.

• A fully automated assembly process reduces errors, ensuring stability and preventing nut drop.

• Before shipment, each cylinder is pressure-tested to guarantee leak-free operation.
