Heavy Duty Water Cooled Cnc Router Spindle Motor 55kw
✔️ 125mm overall length ER25 taper 5.5kw 380V axial preload bearing

This water cooled spindle motor runs your cnc router with smooth torque and stays cool during long jobs. You will use it for metal milling wood engraving plastic routing and heavy duty lathe work where steady speed matters more than hot noise.

✅ 380 volt three phase power input for stable industrial output
✅ ER25 collet size handles common tool holders without extra adapters
✅ C class angular contact ball bearings with axial preload for rigidity
✅ Liquid cooling loop cuts down runtime noise and keeps temps steady
✅ 125 millimeter body width fits standard gantry mounts and enclosures

💡 Does a liquid cooled cnc spindle motor improve cutting accuracy for heavy metal milling tasks? Yup it delivers tighter tolerances by keeping internal temps dead steady while you push the feed rate. This handy rig sips juice from your inverter and kicks back serious low end grunt for tough cuts. - Direct coolant flush drains heat from the bearing races faster than fancy air blowers - Axial preload geometry holds the shaft dead center under heavy side loads - Solid copper windings plus optimized rotor dynamics keep vibration off the table legs - Swap cartridges quick when you match the 380 volt wiring to your existing controller box
