Sorry I know this is not exactly topic related but I'm not standing by and not saying anything on something which is SO WRONG and will potentialy lead others in wrong direction.

A complete load of rubbish, do you know how much water is actually inside a water-cooled Spindle.? approx 250ml or 250grams.! How much does a fan and cowel weigh.?
If the Z axis can't handle that little extra weight then it needs re-thinking.! . . The truth is that if your Z-axis is this weak you cannot fit a Spindle of this size, it's got nothing to do with how it's cooled.

Your comments regards leaks and the damaging the bed is just laughable. They rarely leak when fitted correctly, I've fitted 100+ sets and never had one leak in use unless something caused it, like pipe got snagged or rubbed thru etc. Even then worst case it might wet the spoil board a little but it's not going to wreck the machine.

I think the Shapeoko actually used a SPRING at one time to help keep the router from dropping and not being able to get back up again. So a proper spindle is out of the question.
Cannot blame the Tech because people select the wrong motors and underbuild Z-axis. There is also a reason why we tell people to avoid machines like shepeko with this being just one of them.!

At the end of the day it all comes down to cost.
No at end of the day it comes down to if machine can handle the spindle or not.! . . . Not just the cost. From what your saying you have Shapeko type machine and the simple truth is these weak machines cannot handle large spindles like these. Got nothing to do with how it's cooled and everything to do with build quality.

Comments like your really piss me off because your actually discouraging people from using products which you clearly have little or no experience of using.

Anyone who's used an Air-cooled spindle then switched to WC spindle will say how much better they are. They also don't slag the Tech because the machine is rubbish.
Just the lower noise alone is enough for most people to switch but the fact the duty cycle is pretty much unlimited and the extra power they offer just blows the cheap Air-cooled spindles away.
Even much higher quality air-cooled spindles like HSD cannot match the cheap WC spindles when it comes to the duty cycle. Cheap air-cooled spindles are limited to just a few hours of constant running at high speeds which is useless to any decent machine. WC spindle will happily run for days at full speed.
