Beefy 2.2kW ER20 Air Cooled Spindle Motor For CNC Machines 220V Inverter Ready 0 To 24000 RPM 80mm Diameter 4 Ceramic Angular Contact Bearings Grounded For Inverter 0.01mm Precision Perfect For High Speed Milling And Routing

Single 80mm ER20 CNC spindle, 2.2 kW, 220V input
✔️ 220V input, 0-24,000 RPM, 80 mm dia, ceramic bearings

This high speed, air cooled spindle runs on AC 220V and needs an inverter or VFD to operate. It’s built for CNC milling and routing, delivering precise results with a tight tolerance when paired with a rigid toolholder. The 80 mm body and four ceramic angular contact bearings provide strong rigidity and long life, with proper grounding for inverter safety.

✅ 2.2 kW continuous power for high speed milling
✅ ER20 tool interface for standard cutters
✅ 80 mm (3.15 in) diameter housing, 4 ceramic angular contact bearings
✅ Grounded body for inverter safety; requires inverter/VFD
✅ 0-24,000 RPM speed range; air cooled for continuous operation
