When I went to the local bearing shop here, (Apex International) all they could come up with was the B45 and B46, just like O'reilly's Auto Parts had in their Federal Mogul Catalog.

The Inner is a 1.496 ID and 3.15 OD, Which is still pretty common in industrial use. The outer is .905 and 2.25, which is about as oddball as it gets.

Here's a good link on the subject.

I've thought about having the spindle machined to accept a standardized bearing, probably not worth the effort though. If they ever get scored/damaged it may be something to consider. You could have the inner turned down slightly, so the seal rides on the spindle not the bearing. The outer turned down for a standard bearing and 3/4" spindle nut.
