1.5kW ER11 Air Cooled CNC Spindle, 80mm Shaft, 4 Bearings, 24,000 RPM High Speed Router Spindle, Aluminum Housing, 0.01mm Runout, Quiet Performance For Precise Milling, Ideal For Hobbyist And Small Shop CNC Machines

High-Power ER11 CNC Spindle with Water Cooling, 24k RPM
✔️ 1.5kW ER11 spindle, 80mm shaft, 24k RPM, 0.01mm runout, single

The 1.5kW ER11 water-cooled spindle is a compact, high-speed milling unit designed for hobbyist and small shop CNC machines. It uses high-speed angular contact sealed ball bearings with axial preload to boost stiffness and precision. The water cooling keeps temperatures low and noise down, giving you a quieter workshop. It's well suited for engraving, milling, and light machining when used with a frequency converter.

✅ 1.5 kW continuous power for demanding jobs
✅ ER11 collet compatibility for common tooling
✅ 24,000 RPM no-load speed for fast material removal
✅ Water-cooled design for cooler operation and lower noise
✅ Aluminum housing keeps weight down while dissipating heat
✅ 80 mm shaft diameter for standard mounting
✅ 0.01 mm runout for tight tolerances
✅ High-speed angular contact sealed ball bearings with axial preload

💡 What is a handy way to pick a high-speed ER11 CNC spindle for a hobby shop? This quick guide covers the essentials.

- RPM range should align with the material and tooling for the ER11 CNC spindle - ensure runout is around 0.01 mm for precise engraving and milling - choose a water-cooled design to reduce heat and noise in tight spaces - verify 80 mm shaft mounting and ER11 collet compatibility
