If you have that bearing in hand with the part number, you can run it through Google, NAPA, or Motion Industries
https://www.motionindustries.com/ and possibly they will cross the part number to Timken, or SKF.
Personally, I've been buying NOS Timken/SKF bearings for a few small IH tractors I've been going through, replacing bearings/seals in the rear ends, from a seller on ebay

He has many bearings in stock,and evenmore not listed. If you don't find your bearing doing a search in his online store, send him a message with your part number. He may have them in stock, or has a catalog he can cross to a bearing with the same specs. Everything I have purchased through him have been NOS Made in U.S.A Timken, or SKF bearings at afraction of the cost, in my case through Case/IH. The great thing is, he has free Priorty Mail shipping, and I normally get what I need within 3 days.
I've also bought a few through Rock Auto:
RockAuto , although more seals, than bearings. Just use the part number search at the top left. It only takes a few minutes to save a lot of money.
