✅ Four sealed angular contact bearings for high stiffness and low vibration
✅ Grease lubricated design rated for maximum rotational speed
✅ Built in water cooling jacket minimizes thermal expansion drift
✅ Accepts standard ER25 and ER32 collets up to 13mm tool shanks
💡 What makes a water cooled CNC spindle more handy for heavy metal machining than air cooled alternatives?
The liquid cooling setup pulls heat right out of the housing during tough cuts so you get cleaner edges and longer bearing life.
- Consistent thermal control keeps things from blowing up when you feed steel hard at max RPM
- Tight radial clearance kicks in to stop wobble so your tool bits don't burn out mid-job
- Direct coolant circulation handles sustained material removal rates better than cheap fan setups
- Lower ambient noise levels keep your ears from ringing after a long day in the garage
