Advice sought on ballscrew replacement ball size

06/07/2009· This weekend I yanked the X axis screw on my CNC knee mill and took all 276 balls out and measured about 20% of them. I measured many at .1222" and .1257", with a few in between. I had about .001" lash with this screw and no preload existed so the nut would just freely spin down the screw if held vertical. This is not an adjustable nut. Should I just order some .1250 balls and be done with it ...
