✔️ 20mm bore 42mm outer 8mm wide zirconia single pack qty 1

This 16004 ceramic bearing helps motors spin slicker without heat build up found in metal pieces in industrial gear running fast.

✅ Full ceramic balls resist wear better than steel alternatives
✅ PTFE cage maintains lubrication stability across temperatures
✅ Designed for high RPM spindle applications with minimal noise

💡 What makes full ceramic bearings reliable for heavy industrial machinery?
These units handle higher speeds and extreme temperatures better than standard models.
- These units eliminate electrical arcing risks inside motor housings.
- Lightweight materials reduce overall rotational inertia during startup.
- Non-corrosive nature prevents rust damage on damp shop floors.
