Hard Chrome Plated Rods, Hydraulic Piston Rods, Cylinder Piston Rods, Chromium Rods, Linear Shafts, SBR Shafts, Hard Chrome Shafts, Induction Rods, Induction Shafts, etc.
The diameter range available is from 3mm to 120mm.




Our hard chrome-plated piston rods are manufactured using high-quality materials such as JIS S45C, ensuring durability and performance. The rods undergo precision machining, surface chromium treatment, and heat treatment to achieve a surface hardness of at least HV800 and a surface finish of f7. This makes them ideal for use in hydraulic and pneumatic systems where wear resistance and longevity are critical. The corrosion resistance of our products is tested in our own salt spray laboratory, and the surface hardness reaches HRC55°±2° with a hardened depth of 0.5–3mm. After precision milling and hard chrome plating, the coating thickness is approximately 20 microns ±10%, significantly enhancing wear resistance and extending the service life of the components. We also offer induction-hardened chrome-plated bars, which are produced using advanced techniques on materials like JIS S45C, SAE1045, or DIN CK45. These bars are polished, induction-hardened, and then chrome-plated to a minimum thickness of 0.0005" per side, making them highly impact-resistant and suitable for demanding environments. Applications include linear motion guides, hydraulic cylinder rods, plastic injection molding machines, construction equipment, papermaking machines, printing machines, refrigeration units, food and chemical machinery, agricultural equipment, automotive parts, and shipbuilding. In addition, we provide cold-drawn seamless mechanical tubing (CDS) made from 1020 steel, offering better dimensional accuracy, machinability, and strength compared to hot-finished tubes.
