We offer various chromium-plated piston rods/rods that are used for the production of hydraulic/pneumatic cylinders and guides. You can choose among dimensions from Ø 6mm to Ø 200mm and also in inches.
We offer them in various materials like: CK – 45, 42Crmo4, 20Mnv6, INOX, Nikrom, hardened steel and twice chromium-plated. The outer treatment of the piston rod is within the f7 tolerance. The thickness of the chromium coating is about 10 to 25 my (it depends on the piston rod diameter).

In more difficult working conditions (construction, mining, farming, forestry, etc.), we recommend induction hardening or twice chromium-plated rods. In extreme weather conditions, chromium-plated piston rods are used in the material INOX or Nikrom. Our piston rods comply with the highest standards, are made of quality materials and are also appropriately certified.
Here at Mapro, as the leading manufacturer of hydraulic cylinders, we are aware that the installation of quality hydraulic materials (components) is very important, which is why we only install piston rods of the highest quality in our cylinders. We can cut piston rods to the desired dimensions or treat them according to your requirements.
