Established in 2009, we are a manufacturing company specializing in the production of piston rods and linear shafts. **Quality is the Life of the Enterprise. Your Satisfaction is Our Goal.** Our main products include hard chrome-plated rods, hydraulic piston rods, cylinder piston rods, chromium rods, hard chrome shafts, induction rods, and induction shafts. These are made from high-quality materials such as JIS S45C, SAE1045, and DIN CK45. The hard chromium piston rods produced by our company go beyond standard JIS S45C material. They undergo precision machining and surface chromium treatment, achieving a surface precision level of F7 and a hardness of at least HV800. This enhances wear resistance and extends the service life of the rods, helping customers reduce costs. We conduct corrosion resistance testing in our internal salt spray laboratory. The surface heat treatment reaches HRC55±2°, with a hardened depth between 0.5mm and 3mm. After precision milling and hard chromium plating, the coating thickness measures 20 microns ±10%, significantly improving wear resistance and prolonging rod lifespan. These high-performance components are ideal for heavy machinery, construction equipment, and various heavy-duty applications. Suzhou Weipeng’s chromed steel bars and tubes are widely used in hydraulic and pneumatic cylinders found in agricultural machinery, lifting equipment, material handling systems, waste collection, and more. --- **Main Product Specifications** | Item | Hard Chrome Plated Rod | Induction Hard Chrome Rod | |------|-------------------------|---------------------------| | Place of Origin | Jiangsu, China | Jiangsu, China | | Material | JIS S45C, SAE1045, DIN CK45 | JIS S45C, SAE1045, DIN CK45 | | Length | 1000–6000mm | 1000–6000mm | | Shaft Diameter | 3–120mm | 3–120mm | | Surface Hardness | Without hardened or hardened | HRC58–60 | | Chrome Layer Hardness | Above HV800 | Above HV800 | | Chrome Layer Thickness | 15μm ~ 25μm (Customized) | 15μm ~ 25μm (Customized) | | Surface Hardening Depth | / | 0.8–3mm | | Axis Straightness | 0.15mm/1000mm | 0.15mm/1000mm | | Roughness | Ra 0.2μm~0.4μm | Ra 0.2μm~0.6μm | | Precision | G6/F7 | G6/F7 | --- **Chrome Plated Steel Bars** Our chrome-plated bars are manufactured from medium carbon cold-finished or hot-rolled steel bars, typically in grade 1045. They are centerless ground, polished, and chrome-plated to a minimum thickness of 0.0005" per side. These bars are ideal for most piston rod applications in hydraulic and pneumatic cylinders. **Induction Hardened Chrome Plated Bars** Produced using advanced techniques on JIS S45C, SAE1045, or DIN CK45 steel rods, these bars go through surface removal, polishing, induction hardening, and then hard chrome plating. This results in a durable bar suitable for high-quality piston rods that can withstand harsh environments. **Applications:** - Hydraulic cylinder rods - Farm equipment machinery - Pin stock for equipment attachments --- **Honed Tubes** | Item | Honed Tube | |------|------------| | Raw Material | DIN ST52, SAE1020 | | Pressure & Temperature Classification | High pressure & temperature piping | | Inner Diameter | 40mm–320mm | | Outer Diameter | 50–400mm | | Thickness | 5–40mm | | Length | 7000mm | | Straightness | Max 0.5/1000mm | | Inside Surface Roughness (Ra) | 0.2–0.4um | | Tolerance INT | DIN2391 H8 | **Cold Drawn Seamless Mechanical Tubing (CDS)** This is a cold-drawn 1020 steel tube, produced from pierced hot-rolled bar stock. The cold drawing process improves physical properties, reduces machining costs, and provides better OD and ID uniformity, enhanced machinability, increased strength, and tighter tolerances compared to hot-finished seamless tubing. **Applications:** - Hydraulic cylinders - Rollers - Structural applications - Truck and automotive parts - Heavy equipment - Agricultural components - Axles, suspension parts, shock absorbers - High-speed shafts and rollers - Bearings, spacers, roll cages, and other machined tubular parts Our raw materials are sourced from the most reputable brands in China, ensuring high density and consistent quality. Our products are well-received by clients for their competitive pricing and reliable performance. --- **Wish You a Happy New Year!** **Applications Include:** - Plastic injection molding machines - Working servos - Construction equipment - Rubber molding machines - Papermaking machines - Printing machines - Refrigeration equipment - Food and chemical machinery - Loading equipment - Fiber spinning equipment - Agricultural equipment - Automotive and shipbuilding industries If you are interested in our products, please feel free to contact us: **SUZHOU WEIPENG PRECISION MACHINERY CO., LTD** Address: No.98 Changjiang Road, National Hi-Tech District, 215010, Suzhou, P.R.C Tel: +86-512-68387269 Fax: +86-512-68387269 Website: [www.wepauto.com](http://www.wepauto.com) | [www.chromedbar.com](http://www.chromedbar.com)
