Help Me Find these Tiny Ball Bearings?

The pedals on my red bike are shot and in need of an overhaul. I know this can be a frustrating job and there is a valid argument for not bothering to overhaul a cheap pedal but I'd rather salvage these pedals.

But the bearing are super tiny and the these places don't have them:

1. Blue City Cycles

2. Joe Harris Hardware

3. The hardware street on Halsted across the street from Nana

4. The Home Depot - south loop

I don't have a micrometer so I'm not sure the exact size, but here is a picture:

Does anyone know a local or online source for such a small bearing? 

thanks!

What kind of bike is it? What kind of pedals are they? If your ocal bikes shop doesnt have the bearings then it is something strange. Park tools makes a ruler that has ball bearing measurements... http://www.amazon.com/Park-Tool-Spoke-Bearing-Cottergauge/dp/B000OZ..., but if this is some irregular size of bearings used in most bicycles, which is possible, you will have to use calipers and measure them as mentioned previously and order them from a machinist website or maybe Amazon. Remember if you replace one you have to replace them all.

3/32 it is:

Turned out that we had a dial caliper in the bike shop all along. d'oh!

The shiny one is from McMaster-Carr. They sent me 100 for a bit over $12. I cannot recommend their online ordering experience - it never listed the shipping cost, I never got an invoice despite requesting one, there was no confirmation email - I did get the package two days later and was happy to at least support a local company.

Now comes the hard part!

They're probably 3/32. I was just looking into this for my pedals but decided that for my minor clicking I'd try to just replace the grease first. Anyway, I found them for sale at Amazon. Not local but it looks like that's been tough. http://www.amazon.com/gp/aw/d/B002BBK7YA?pc_redir=1407322598&ro...

From my reading, grade 25 is good enough for pedals. The smaller the number, the more precise the machining of the bearings.

Unusual service from Mc Master Carr.  I use them all the time.  Online ordering takes a few orders to get used to but if you are familiar with their print catalogue, its similar. They always confirm the order with an email immediately, follow up with the shipping invoice (including shipping cost) and deliver promptly.  At work if I order before 10am, I can generally get it the same day in late afternoon.  After 10am I have it the next morning.

I'm not going to gloat.

Glad you got it to a caliper first, though.

Gloat on bro! 

It took just under an hour to overhaul both pedals. It was not fun exactly, but I'm glad I did it. Each pedal used 28 bearings! I guess a lot more fell out than I had originally thought when I opened up the first pedal. I was super careful about opening up the other pedal today so I could count the bearings in each race to make sure that I used the correct number.  I don't have enough left from my batch of 100 to do it again... in retrospect, assuming I do it at least one more time, I would have  saved money by getting 1000 from Grainger for $20 or so.
