Stainless Iron Rolling Needle

Stainless Iron Rolling Needle Product Overview

Guangyang's strength lies in producing high-end needle rollers with a diameter of 0.5mm x length of 1.5mm to 6mm x length of 40mm and a precision of 0.001μm. The main products are needle rollers, made from materials such as axle steel, stainless steel, stainless iron, high carbon steel, ZOCM, and other customized materials.

Core Advantages

1. Economical Rust Prevention

   • Stainless iron needle rollers are more corrosion-resistant than carbon steel: containing chromium (12%~18%) forms a passivation film, resisting moisture and weak acid/alkali environments (superior to ordinary GCr15 needle rollers). The cost is lower than 300 series stainless steel: suitable for applications with limited budgets but requiring basic rust prevention.

2. High Hardness & Heat Treatable

   • Martensitic stainless steel (such as 410, 420): after quenching, the hardness can reach HRC 50-55, and the wear resistance is close to that of bearing steel.

   • Surface strengthening options: chrome plating, nitriding, and other treatments can further improve wear resistance.

3. Moderate High Temperature Resistance

   • The working temperature of stainless steel needle roller s is ≤300°C: superior to ordinary steel needle rollers (150°C), but lower than 300 series stainless steel (500°C).

4. Magnetic Characteristics

   • Magnetic: Stainless steel needle roller s are suitable for scenarios requiring magnetic adsorption positioning (such as automated sorting equipment).

Common Applications Include:

• Automotive Industry: Components such as gearboxes, clutches, steering systems, engine camshafts, and chassis suspensions utilize needle roller bearings (containing needles) for efficient transmission and support.

• Machinery Manufacturing: Needle rollers can adapt to the installation requirements of confined spaces in machine tool spindles and guideways, transmission components of textile machinery, and roller supports in printing machinery.

• Hydraulic and Pneumatic Equipment: Moving parts such as pistons and plungers inside hydraulic pumps and motors use needle rollers to reduce friction and improve equipment efficiency.

• Medical Devices: The rotating or sliding structures of some precision medical devices require needle rollers to provide stable support and low-friction movement.

• Construction Machinery: In hydraulic cylinders and joint components of equipment such as excavators and loaders, needle rollers can withstand large loads and adapt to complex working conditions.

The core requirement in these scenarios is to save space using the slender structure of needle rollers, while simultaneously reducing equipment wear and improving operating efficiency through rolling friction.
