CK45 Chrome Plated Piston Rod & Chrome Hollow Bar Manufacturer
Model: CX-10
Brand: CHENGXIN
HS Code: 841290
MOQ: 1 Ton
1. Premium CK45 Carbon Steel Chrome Plated Piston Rod (Solid)
Our solid ck45 chrome plated rod is engineered from high-quality carbon steel, offering exceptional tensile strength and core stability. The ck45 carbon steel chrome plated piston rod undergoes rigorous peeling, precision grinding, hard chrome plating, and polishing. This results in a flawless, mirror-like finish with unparalleled wear and corrosion resistance.
These solid rods are the industry standard for standard hydraulic cylinders, pneumatic systems, machinery shafts, and heavy-duty linear motion applications where maximum dynamic strength under load is required.
2. Hard Chrome Plated Steel Hollow Bar (Light-Weight Solution)
When weight reduction is critical without sacrificing structural integrity, our hard chrome plated steel hollow bar is the ultimate solution. Manufactured from premium seamless mechanical tubing, the chrome plated hollow piston rod significantly reduces the total weight of the cylinder assembly.
As a dedicated hollow cylinder rod factory, we supply the hollow chrome plated rod globally. It is particularly suited for multi-stage telescopic cylinders, mobile lifting equipment, and agricultural machinery where minimizing weight improves energy efficiency.

Frequently Asked Questions
Q1: Do you supply both solid and hollow chrome plated rods?
A: Yes, we offer both types. The chrome plated hollow piston rod is made from seamless tubes with hard chrome plating, while solid rods are machined from solid steel bars like CK45.
Q2: What is your standard chrome plating thickness?
A: Standard chrome thickness is 20–30μm, but we can provide up to 50μm upon request.
Q3: Are your rods suitable for telescopic cylinders?
A: Absolutely. Our hard chrome plated steel hollow bars are ideal for multi-stage telescopic hydraulic cylinder use due to their weight-saving properties.
Q4: Do you export globally?
A: Yes, we support ISO-compliant manufacturing and OEM customization, exporting to more than 30 countries including Germany, Brazil, Turkey, India, and Southeast Asia.
