Ok, I'm stumped. Question for Gary (ZAPP)

THe link to the double ball nuts is here

the ball nuts i have in stock are pre loaded to give a max backlash of 20 micron.
If you want a zero backlash nut, this will need to matched to the ball screw at the factory.

Sounds promising, I'd probably only need to lengthen the ends a bit, maybe deepen the circlip groove a tadge. A couple of flat spots would be handy.

Can I find the dimensions and details for the double nuts on your website? They seem to be hidden under pre-machined screws, so when you click for info you get told about end machining rather than nuts :confused:

Last time I bought a "zero backlash nut" it was from that other bunch. Turned out I had to crush it sideways. A bit tricky when it's buried under a milling table

And the ball nut is the FDU type
