All - found out today that my order was declined because the part is "no longer available from the manufacturer" - they should really update their system, if that's the case.

I ended up ordering some 6301 bearings off Amazon to replace the dead one - got a few different kinds just to see what might be best. One's an SKF (double sealed), one's a Nachi (I've heard good things about them), and a pair of generic sealed ones from VXB. I'm probably going to install the Nachi (or I might just wait for the SKF - it seems like something I could install and it would take forever to fail).

A friend of mine has a 20 ton press, plus I bought a few extra tools to help (a bearing puller, and a bearing install kit for metric sizes). Plus there's Cobrajet's offer above. One way or another, I'll get this thing fixed!

Thanks!
