Don't make the resolution of your inspection tools too fine. :wink:
If you wanna drive yourself nuts, this unit indicates to 10 millionths.
I use it for things like comparing dowels for inspection set ups, piston pins for roundness, etc. Can certainly do ball bearings.
Assume your 3 posts will be ball bearings? They are incredibly close tolerance.
Though if careful not to rotate/move them between inspections, it wouldn't matter.
