ballnut housing and floating end ballscrew assembly

[John S]

OK got it now. What machine is it for ?

I'm guessing we're talking loads here? it's a rather non-standard application with a z-axis alone, nothing else, as I need precision positioning in the vertical. Max loads would be maybe 1-5% of the maximum load capacity of the ball screw given to me by Chai (quoted figures where 4kN for static load and 3.5kN for dynamic load). The Z-axis runs on 15mm Hiwin rails, which are a pain in the ass to use, as their profiles are super low, which is why I've got this depth problem.

Put some gauge plate packers under the hiwin rails to get more clearance ?
