I have hard times believing that they are really made to such
specs. (or that skateboards need such precision)


I was at a Favnir or SKF class a few years ago. They said they didn't make
an ABEC 1 and a 3 was likely to be a 5 since their goal is to make good
bearings.

When were the ABEC spec's first published? I would guess today just
about any new machine used to make ball bearing is 1000X better than
is was back then. A manufacturer would have to screw up bad to make
an ABEC 1 today, IMHO.
