Stainless Steel Needle Roller

Stainless Steel Needle Roller 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 of materials such as steel, stainless steel, stainless steel, high carbon steel, ZOCM and other custom materials.

Core Advantages

1. Excellent Corrosion Resistance

   • Rust and Acid Resistance: 304/316 stainless steel resists water, steam, and weak acid and alkali corrosion, suitable for humid, chemical, and marine environments.

   • Food-Grade Safety: Stainless steel needle roller s meet FDA standards and can be used in food processing, medical equipment, and other hygiene-sensitive industries.

2. High Hardness & Wear Resistance

   • 440C Stainless Steel: After heat treatment, the hardness reaches HRC58-62, approaching the wear resistance of bearing steel (GCr15).

   • Long Service Life: Stainless steel needle roller s have a high surface finish (Ra≤0.2um), reducing friction loss.

3. High Temperature Resistance

   • Stable up to 500℃: Stainless steel has better oxidation resistance than ordinary steel at high temperatures, making stainless steel needle roller s suitable for high-temperature bearings (such as baking equipment).

4. Lightweight & Low Density

   • The density of stainless steel needle roller s (7.9g/cm3) is slightly lower than that of carbon steel, making it suitable for weight-sensitive applications (such as aerospace and robotics).

5. Non-magnetic or weakly magnetic

   • 304/316 Non-magnetic: Stainless steel needle roller s are suitable for applications with total magnetic field interference, such as MRI equipment and electronic instruments.

   • 440C Weakly magnetic: Can meet some special requirements.

Common Applications Include:

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

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

• 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: Hydraulic cylinders and joints of equipment such as excavators and loaders use needle rollers to withstand large loads and adapt to complex working conditions.

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