Thought I'd put this up in case anyone needs some, or might want some for a stash. I discovered recently when I dug into my Supermax clones spindle that the bearings in there now are just regular grade 7207s. Given the class of this machine (fairly high quality Taiwan build, some on Practical Machinist allege they're a bit more solid than the real deal), I doubt it was originally fitted with German SKF (one 7207 BEGP and one 7207 BEP), and the marks on the nose cap suggest someone has been there before, but maybe I'm wrong.
Anyway, I found this listing on eBay: https://www.ebay.com.au/itm/NEW-FAFN...72.m2749.l2649 (https://www.ebay.com.au/itm/NEW-FAFNIR-2MM207WI-DUL-SUPER-PRECISION-BEARING-SET-2MM207WIDUL/114037333021?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649) and ordered them. Wasn't quite 100% sure that they were a matched pair as they should be, but there appeared to be two bearings in the photo, and the DUL in the part number denoted they should be. They arrived a week or so back, and they appear to be exactly what they should be. Little piece of paper points out that both the inner and outer races have a small burnished circle to denote installation alignment, and that is indeed the case. At $205 posted, you'll be going to beat that price, everywhere else I looked for the same spec of bearing was $350+. Just be a little careful if you see some cheaper related items, make sure they're actually a matched pair. I did find a seller cheaper, but he appeared to be selling a single bearing.
I also found that RS Online seem to have sharpened their pencil somewhat on some items, as I grabbed a C2 class SKF 6206 for the top of the spindle from them for $25, free post. Debatable whether C2 class is necessary here, but for the price I figured I may as well.
