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.
