2.2KW ER20 Air Cooled Spindle Motor With 80mm Housing Four Ceramic Bearings 400Hz CNC Spindle For Engraving And Milling 3-Phase VFD Ready Beefy Torque Durable Air Cooling For Precision Milling

Single 2.2kW ER20 Air-Cooled Spindle, 80mm Housing
✔️ 80mm housing, ER20 collet, 2.2kW, 0-24k rpm, 400Hz

This high-power ER20 air-cooled spindle motor is designed for engraving and milling on CNC routers and small milling machines. It features an 80 mm body, 2.2 kW power, and four ceramic bearings to deliver precise, smooth rotation. The spindle runs on 220V and is compatible with 3-phase VFDs for variable speed control, while air cooling keeps temps in check during long jobs.

✅ Four fully sealed angular contact ceramic bearings (two 7005 P4 DT and two 7002 P4 DT) for stiffness and long life.
✅ ER20 collet accepts tooling from 1 to 13 mm for broad engraving and milling options.
✅ 80x224 mm body fits standard CNC spindles; runout under 0.01 mm for tight tolerances.
✅ 0-24,000 rpm speed range, 0-400 Hz drive; 2.2 kW at 220 V; air-cooled design.
