Came across these http://www.anaheimautomation.com/man...ct%20Sheet.pdf and wondering if anyone has used something similar?

Could they be used instead of a rotating nut design on a CNC router?

Hi John, yes, we used similar for a special order of mini cnc machines. The only restriction was the spindle diameter, a short stroke of 400mm for 10x4 spindle

They could, but they do sacrifice several things over the nut design.

The nut design has a smaller lowest replaceable unit. The Anaheim things force you to replace the whole motor and lead screw. Also, in design's like Joe's 4x4 Hybird, the motor is static relative to the motion of the screw, which means that the cabling is simpler, at least for the X-axis. This also means that the motor can be placed where it won't get chips or other disgusting things on/in it,which improves the service life of the motor. For larger machines or something like a Z-axis, the Anaheim thing's lead screw is a tad small. However for an application like a pick-and-place machine or other non-cutting type machine, the Anaheim things would be ok, despite their smaller ball screw. Additionally, a mounting system for the Anaheim things could be more easily fashioned, compared to mount for a nut.

Having never used this Anaheim product, everything I said is based on what I saw in the link you posted. I think they would be very useful in the right applications, but I have to find sliver bullet (A single part or configuration that works everywhere, 100% of the time.) for designing things.
