You would be able to produce near perfect ball bearings in zero G so they'd last almost forever.

Respectfully,
Even if you could get far enough out to be free from any gravitational forces whatsoever, building a craft that could house a smelter to make the bearings, and getting it out there, and bringing the bearings back, would result in them costing several $ bazillion each.
I am curious how they would perfectly control the finished diameter of the solidified blob, and how a zero G environment would affect making a bearing race, inner or outer.
I must be missing something.
