Hollow Chrome Plated Bar
The Hollow chrome-plated shafts play an important role in many industrial fields due to their unique structure and excellent performance. They are an indispensable key component in modern machinery manufacturing...
Introduction
The hollow chrome-plated bar (also called a hard chrome-plated hollow cylinder) is a precision-engineered metal component consisting of a tubular steel bar with an electroplated chromium coating. It offers superior corrosion resistance, wear durability, and low friction properties for industrial applications.

Product Features
Lightweight: The hollow structure significantly reduces the weight of the shaft and the overall weight of the mechanical equipment.
High hardness and wear resistance: The chrome plating layer has high hardness and good wear resistance, which can effectively increase the service life of the shaft.
Corrosion resistance: The chrome layer has good corrosion resistance to a variety of chemical substances and is suitable for use in harsh environments.
Good mechanical properties: The Hollow hydraulic chrome bar is usually made of high-quality steel (such as 45 steel, bearing steel, etc.) and has good strength and rigidity.
Product Applications
Automobile manufacturing: Hollow chrome plated rods are used for motor shafts, transmission shafts and half shafts of new energy vehicles, which can effectively reduce vehicle weight and improve transmission efficiency.
Aerospace: Chrome plated hollow rods can be used as aircraft landing gear support shafts. Due to their lightweight and high-strength characteristics, they meet the strict requirements of the aerospace field.
Mechanical transmission system: It is widely used in hydraulic pneumatics, engineering machinery, plastic machinery, packaging machinery, printing machinery and other fields as key components such as transmission shafts, guide shafts or support shafts.
Robotics: The internal space of the hollow chrome steel shaft can be used to insert measuring wires, compressed air or lubricating oil, which is suitable for robot arms
