Re: [CAD_CAM_EDM_DRO] Ballscrew balls ?

hi harko-

i measured the balls in the thomson/danaher non-preloaded nut (just happen
to be reballing them) and they're all 0.1245". i ordered a bag of both
1/8" (which are indeed 0.1250" and do flow through the race) and 3.5mm.

the 3.5mm's don't fit through the race (found out the hard way but had to
try it).

interesting, what kind of ballnuts have different sized balls and why?
