I think you’re right, it seems to be a bit too far off. With no nuts on the bolts there was a gap between the bearings and the conduit.
I just gave it a try after tightening the bolts, it removed the slop so all three bearings were now touching the conduit but it wasn’t overly tight either. I’ve a feeling that when the coating wears off the conduit then the slop will return.

I think the best thing to do is just get more conduit. It’s cheap so there’s no point in sacrificing the accuracy of the machine for the sake of tiny extra cost.
I’ll just measure the conduit at the wholesaler when I’m getting it.

Should all of the bearings be in contact with the conduit even without the bolts tensioned?
