    New ball bearings are still likely significantly smoother than the earth. Old worn out ball bearings might be rougher.

      After doing a bit of digging it looks like Earth would be comparable to a 1 inch grade 1000 ball bearing.

      mobile link, sorry

      God damn ball bearings get down to some crazy high tolerances.

      I’m happy I dig some digging into it.

      Edit: Grade 1000 is a really low grade ball bearing, thought I should clarify that.
