RE:RE:RE:RE:From LinkedinAfter a bit of thought I think there maybe another round crate which is not in the picture.
If so, then I would guess they are the hydrostatic bearings for the mills.
I'm f***ed if I know, but the latter makes more sense since the mills end caps arrived at the same time and the size looks right to me.

This is what we can expect for a typical plant build and how to recharge the mills with new balls and rods.(sounds a bit dirty hey ?) lol :-
