Can anyone offer advice on ballnut quality/price. Ballscrew specification is easy to find - very little information on ballnuts which may be equally critical.
That would seem to say 20mm ballnuts have much better rigidity than 16mm and 20mm dia you have to load 25kg for 1Um movement? If true I would not need to look for better quality nuts - no mention of backlash though, is it assumed to be zero?
