Copper Needle Roller

Copper Needle Roller Product Overview
GY specializes in manufacturing high-end needle rollers with diameters ranging from 0.5 mm × 1.5 mm to 6 mm × 40 mm, achieving a precision of 0.001 μm. Our products are primarily made of bearing steel, stainless steel, stainless iron, high-carbon steel, ZOCM, and other customizable materials.

Copper Needle Roller Core Advantages

1. Self-Lubricating Properties: Copper alloy material inherently offers excellent self-lubrication, making copper needle rollers ideal for applications where frequent lubrication is impractical or grease contamination is prohibited (e.g., food machinery and medical equipment).

2. Vibration Damping and Noise Reduction: The low elastic modulus of copper needle rollers effectively absorbs vibrations, reducing operational noise by over 30% compared to steel needle rollers.

3. Corrosion Resistance: Bronze material performs exceptionally well in humid, acidic, or alkaline environments, making it particularly suitable for chemical processing, marine, and other corrosive applications.

4. Anti-Galling Properties: Under boundary lubrication conditions, copper needle rollers are less prone to galling with shafts, preventing sudden failures.

5. Rapid Run-In: Copper needle rollers have a short initial run-in period, quickly achieving optimal performance and fit.

Copper Needle Roller Common Applications

• Automotive Industry: Applications such as transmissions, clutches, steering systems, engine camshafts, and chassis suspensions utilize needle roller bearings (incorporating needle rollers) for efficient power transmission and support.

• Machinery Manufacturing: Needle rollers are used in machine tool spindles, guide rails, textile machinery transmission components, and printing machine roller supports, where their compact design accommodates limited space.

• Hydraulic and Pneumatic Equipment: Needle rollers reduce friction in pistons and plungers within hydraulic pumps and motors, enhancing operational efficiency.

• Medical Devices: Precision rotating or sliding structures in medical equipment rely on needle rollers for stable support and low-friction movement.

• Construction Machinery: Needle rollers withstand heavy loads and adapt to complex working conditions in hydraulic cylinders and joint parts of excavators and loaders.

These applications leverage the slender structure of needle rollers to save space while reducing equipment wear and improving operational efficiency through rolling friction.
