For the Tube:
We utilize 25Mn steel, identical to the material used by original hydraulic cylinder manufacturers.
The surface undergoes sandblasting, followed by a baked painting process—starting with primer application and drying, then finishing with a topcoat, ensuring a double-layer protective finish.
For the Rod:
The piston rod is fully heat-treated for enhanced durability.
It undergoes high-frequency induction hardening, achieving a hardness level of up to 55.
The surface is coated with a layer of hard chrome plating for superior wear resistance.
For the Seal:
We incorporate imported seals from Japan's NOK and the US's SKF, ensuring an oil leakage rate of the cylinder remains below 1%.
