General Mach Discussion / Re: Anti-Backlash Nut Setting

Hi,
in theory the two bearings should be a matched pair of angular contact bearings. They are ground such that when the two bearings are clamped together tightly the correct
amount of preload is applied...it does not require adjustment by torquing the clamping nut.
Given the battle you've already had with machining tolerances is questionable whether the manufacturer used a matched pair of bearings.
If the bearings are matched there should be no increase in rotational drag no matter how tight you tighten the nut. Is this the case?
