Silicon Nitride Ceramic Wire Wheel

Applications of  Si3N4 Ceramic Wire Wheels

• Scenario 1: Cable Manufacturing Plant

In high-speed cable extrusion lines, silicon nitride wire wheels are used to guide and tension copper or aluminum wires. Their low-friction surface reduces wire breakage and improves line efficiency.

• Scenario 2: Transformer Coil Winding

During transformer production, precise wire routing is critical. These ceramic wheels maintain dimensional accuracy under thermal stress, ensuring consistent coil geometry.

• Scenario 3: Motor Stator Winding

In the motor manufacturing industry, silicon nitride rollers are utilized in automated winding machines. Their electrical insulation and wear resistance reduce the frequency of maintenance and downtime.

Si3N4 Ceramic Wire Wheels Usage Instructions

Installation:

• Ensure the shaft and bore are clean and aligned.
• Use appropriate torque when mounting to avoid cracking.
• Avoid metal-to-ceramic impact during installation.

Storage:

• Store in dry, vibration-free environments.
• Avoid stacking without protective layers.

Cleaning:

• Use isopropyl alcohol or neutral detergent.
• Avoid abrasive tools that may scratch the surface.

Common Mistakes:

• Over-tightening mounting screws may cause microcracks.
• Using in corrosive environments without proper sealing may reduce the lifespan.
