There should be a number or set of numbers on the bearing, you may need to clean it thoroughly and / or use a magnifying glass or play with lighting in order to read them. Put those numbers into a search engine, and you will probably get links to bearing supply houses...
Those numbers will describe the bearing if it is an industrial standard one (most are). Worst case, pull one out and take it to a bearing supplier (most decent sized cities will have at least one)...
Most bearings don't have an extension like the one you have in the picture, if you can't find one that does have the extension, you may need to get a spacer or have one made to account for the difference. Aside from possibly being more of a pain to put together, this won't hurt anything, and bearings w/o the extension are likely to be less expensive.
