Prouduct Description

Product Show

Our hydraulic cylinders are built with precision and durability in mind:

• Piston rods undergo overall conditioning and high-frequency surface hardening, achieving a hardness of up to 55. A hard chrome plating ensures longevity.

• Forged steel is used for rod ends, tube ends, and cylinder covers, welded automatically for smoother, stronger joints.

• Cylinder tubes are made from 25Mn steel, identical to OEM materials. They are sandblasted, primed, and coated with two layers of baked paint for superior protection.

• We use Japan NOK and US SKF seals, keeping the oil leakage rate below 1%.

• Our fully automated assembly line minimizes human error, preventing issues like nut drop and ensuring production stability.

• Every cylinder is pressure-tested before shipping to guarantee zero oil leaks.
