Pink caged ceramic pulley designed as precision coil winding tensioner accessories to prevent wire jumping during winding processes. These wire guide pulleys ensure stable tension control and protect enameled wire insulation in industrial coil winding machines.

• Prevents wire jumping during coil winding operations
• Ultra-fine polished ceramic surface with Ra0.2 finish
• High-speed bearing for smooth wire guidance
• Controls sliding distance under 0.2mm to protect wire film
• Stabilizes tension throughout winding process
• Suitable for radical direction changes in winding paths

Specifically designed for QH001~QH007 series wire jump preventers used in coil winding machines where precise wire guidance and tension stabilization are critical for manufacturing quality coils and transformers.
