This is not for me, it is for my friend, who does not use usenet. He
needs some bearings and he wants to find standard industry
designations (like 6011, etc). I checked machinery handbook and did
not find that sort of table, even though it talks at length about
bearings.

He needs some 1" ID by 2" OD bearings. I know that McMaster has them,
but he (and I) is not sure whether there are different specs. And he
is hoping he can find a better deal on ebay if he knows what codes to
look for. He wants to basically make a wood shaper that would spin at
23,000 RPM. (!).

Well you better get him to think expensive or smaller, as standard
1" bore ball bearings are limited to 12,000 rpm when grease lubed,
15,000 when oil lubed. If you decrease the OD, 18,000 is attainable
if oiled. From the SKF manual.
