Jiangsu Zijun International Trade Co., Ltd. , https://www.zijunplastic.com
Suzhou Weipeng Precision Machinery Co., Ltd. is a leading manufacturer based in Suzhou, a city known for its economic development and proximity to Shanghai, a major international port. Established in 2009, the company specializes in the production of high-quality piston rods and linear shafts for hydraulic and pneumatic systems.
Quality is the lifeblood of our company. Your satisfaction is our ultimate goal.
Main Products:
We provide manufacturers of hydraulic and pneumatic cylinders with a wide range of high-quality tube and piston products, including:
Materials Used:
JIS S45C, SAE1045, DIN CK45
Our hard chrome-plated piston rods are manufactured using advanced techniques. The process includes precision machining, surface chromium treatment, and heat treatment, resulting in a surface precision level of **f7** and a hardness of **Hv800 minimum**. This not only enhances wear resistance but also extends the service life of the rods, offering long-term cost savings for our customers.
The corrosion resistance of our products is tested in an internal salt spray laboratory. Before final processing, the rods undergo surface heat treatment, achieving 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 prolonging the rod's lifespan.
These high-performance components are ideal for use in heavy machinery, construction equipment, and various industrial applications where durability and precision are critical.
Our chromed steel bars and tubes are widely used in the fabrication of hydraulic and pneumatic cylinders found in agricultural machinery, lifting equipment, material handling systems, waste collection devices, and more.

Our chrome-plated steel bars are made from medium carbon cold-finished or hot-rolled steel, typically in 1045 grades. They are centerless ground, polished, and chrome-plated to a minimum thickness of 0.0005", with 0.001" per side. These bars are specifically designed for use in 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 hard chrome plating. The result is a durable, impact-resistant bar suitable for high-quality piston rods that can withstand tough environments.

Cold Drawn Seamless Mechanical Tubing (CDS):
This is a cold-drawn 1020 steel tube, produced from piercing hot-rolled bar stock. The cold drawing process enhances the tube’s physical properties and reduces machine time costs. CDS tubing offers better OD and ID uniformity, improved machinability, increased strength, and tighter tolerances compared to hot-finished seamless products.
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, and other machined tubular parts
Our raw materials come from the most reputable brands in China, ensuring high density and consistent quality. Our products are well-received by clients due to their competitive pricing and excellent performance.
Applications Include:
- Plastic injection molding machines
- Working servos
- Construction equipment
- Rubber molding machines
- Papermaking machines
- Printing machines
