CNC Z axis motion kit. Taken from a light weight CNC machine I was building years ago and never got around to using. 16mm 300mm long rails with 3 carriage per rail. 10mm pitch lead screw with shortened nut carrier to maximise travel. This had a total travel of 160mm when assembled. I have similar X and Y axis kits available with 750mm rails, NEMA 23 motors, belts and pulleys, and lots of other CNC bits for sale that I haven't listed let. Message me for details.

Compared with the sliding screw pair, the driving torsion of the ball screw is 1/3. There are many balls between the screw shaft and the screw nut, which can achieve higher motion efficiency. Smoothly curve ball screw drive designer, work more smoothly and naturally.
