These spindles look attractive but there are almost no specifications at all.
What are the part numbers and ABEC class of the bearings, what is the bearing arrangement (duplex on the nose, etc.), what is the guaranteed spindle runout, etc?
Is the water cooling intended to be once-through or can it be recirculated from a reservoir? Is there a specified maximum water inlet temperature? Is the duty cycle 100% with the water cooling?
Thanks,
