Chrome Plated Hydraulic Piston Rod for Hydraulic Cylinder

**Product Specifications** --- **Company Overview** Suzhou Weipeng Precision Machinery Co., Ltd. is located in Suzhou, a city known for its strong economic development and proximity to the international port of Shanghai. Established in 2009, we specialize in the production of high-quality piston rods and linear shafts for hydraulic and pneumatic systems. Quality is the core value of our company. We are committed to delivering products that meet the highest standards, ensuring customer satisfaction through consistent performance and durability. **Main Products:** - Hard Chrome Plated Rod - Hydraulic Piston Rod - Cylinder Piston Rod - Chromium Rods - Hard Chrome Shaft - Induction Rod - Induction Shaft Our materials include JIS S45C, SAE1045, and DIN CK45. The hard chromium piston rods we produce are not only made from premium materials but also undergo precision machining and surface chrome treatment, achieving a surface hardness of at least HV800 and a surface finish of F7. This ensures superior wear resistance and a longer service life, helping our customers reduce maintenance costs. We conduct corrosion resistance tests in our own salt spray laboratory. Our rods feature a surface heat treatment with a hardness of HRC55±2° and a hardened depth between 0.5mm and 3mm. After precision milling and hard chrome plating, the coating thickness reaches 20 microns ±10%, significantly improving wear resistance and extending the rod's lifespan. These products are ideal for heavy machinery, construction equipment, and various industrial applications. Our chromed steel bars and tubes are widely used in agricultural machinery, lifting equipment, material handling systems, waste collection, and more. --- **Company Capability** [Image: Chrome Plated Hydraulic Piston Rod for Hydraulic Cylinder] [Image: Chrome Plated Hydraulic Piston Rod for Hydraulic Cylinder] [Image: Chrome Plated Hydraulic Piston Rod for Hydraulic Cylinder] [Image: Chrome Plated Hydraulic Piston Rod for Hydraulic Cylinder] [Image: Chrome Plated Hydraulic Piston Rod for Hydraulic Cylinder] [Image: Chrome Plated Hydraulic Piston Rod for Hydraulic Cylinder] Below are the main product specifications for your reference: | 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 steel bars are manufactured from medium carbon cold-finished or hot-rolled steel, typically in SAE 1045 grades. These bars are centerless ground, polished, and coated with a minimum chrome layer of 0.0005" per side. They are ideal for most piston rod applications in hydraulic and pneumatic cylinders. **Induction Hardened Chrome Plated Bars:** These bars are produced using advanced techniques on JIS S45C, SAE1045, or DIN CK45 steel rods. The process includes surface removal, polishing, induction hardening, and hard chrome plating. The result is a durable bar suitable for harsh environments. **Applications:** - Hydraulic cylinder rods - Farm equipment machinery - Pin stock for 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. It offers better dimensional accuracy, enhanced machinability, and higher strength compared to hot-finished tubing. It is widely used in 3D printers, textile machinery, hydraulic cylinders, rollers, and structural components. Our raw materials are sourced from reputable Chinese brands, ensuring high density and consistent quality. Our products are well-received by clients for their competitive pricing and reliable performance. **Applications Include:** - Plastic injection molding machines - 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 --- **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) Wishing you a happy and prosperous new year!
