What does the B2 mean ? .010 or .020 under size ?

In the suffix, "B" would indicate .010" under size. The "2" in that suffix would be an engineering change but that won't change the size. My books don't cover the -B2 suffix bearing part number and it's a 1953 edition.

It may just be that the later stuff was out sourced and made by different manufacturers.
