Excellent corrosion resistance.
Good insulation performance and no static electricity.
Self-lubricating function, reducing pollution.
Thermal expansion coefficient close to steel, resulting in good dimensional stability.
Zirconia ceramic guide wheels are industrial guide wheel components made of zirconia ceramic material, primarily used for guiding and transporting wires and filaments.
1. Textile industry: Used for yarn guiding, significantly reducing breakage rates.
2. Semiconductor packaging: Enables nanoscale guiding of wafer cutting lines.
3. Lithium battery manufacturing: Used for high-speed transport of ultra-thin copper foil.
4. Automotive industry: Maintains consistency of copper wires in motor windings.
5. 5G communication: Ensures the stability of high-frequency signal transmission.
Technical Parameters and Specifications
1. Diameter Range: 80mm to 200mm.
2. Wheel Width Design: Greater than twice the maximum wire diameter (e.g., 11mm wheel width for conveying 5mm wire).
3. Inner Bore Diameter 25mm: Suitable for standard motors.
4. Inner Bore Diameter 30mm: Suitable for high-speed industrial chains.
5. Machining Accuracy: Up to 0.001mm.
