where can I buy a ball bearing in San Francisco/San Jose in US?

Try:
Kaman Bearing & Supply Corp 316 Littlefield Ave S San Francisco, CA 94080
(650) 589-6800

Or without leaving home you can get one from McMaster...
6680K17 Single-Row Angular Contact Ball Bearing-ABEC3 for 30mm Shaft Diameter, 62mm Outside Diameter In stock at $55.91 Each
I'd expect the bearing to be about $10 cheaper from Kaman. Motion Industries is another supplier that I'm sure will have a branch in your area.

I've used these guys and have been pleased. Also phone book showed: Bearing Agencies 415-621-8363 I've never dealt with them.

Bearing Engineering has never failed me. I go to the one in Emeryville, but I know they have several locations. How do I know? Because when they don't have what I need in Emeryville, they get it from one of their other stores within a day.

Thank you all very much for your replies. I just arrived at CA early this morning. It's a lovely day today :)
My friend asked me to buy this very specific type of bearing from US. He gave me a type of "7206" and a rating of "C". He only mentioned it's some kind of quality rating of the part. From A, B to C, and C being the best (maybe there is D or more, I don't know...)
However, I couldn't find this rating anywhere in the websites you guys gave. Do you know what this rating means? Is it an international rating? Or does it have another name/term in U.S.?
Another question, my friend said the bearing should be sold in pairs. I found VXB.com is selling 7206B at $29.99 per pair. But mcmaster.com is selling at $55.91 *each*. Is that $55.91 for only one? Why is the difference so big?
Thanks again in advance.
