Bearing sizes

Easy question from a noobie:
What would be the most common bearing sizes? (hubs, pedals, headset, BB)

I'm working mostly with vintage bikes, and will be looking for a bearing supplier to order a batch for overhauling.

5/32, 3/16 and 1/4 are the most common. Campagnolo front hubs are unique and use 7/32 and some one piece cranks use 5/16"

Also for your purposes buy grade 100, or 300. If you find yourself working on high end bikes you might want to spring for grade 25.

Thanks for the help.
If I can't find a supplier I'll order some from that auction site.

Search bearing balls, not ball bearings, and you'll find a number of sources, then it's a question of minimum orders.

You'll also want 1/8" balls if you rebuild freewheels or '60s/'70s Schwinn/Huret derailleurs.

Depending on your location you may find you can get them locally.

Don't tell me what "should" be - either it is, it isn't, or do something about it.

If you think I'm being blunt take it as a compliment - if I thought you were too weak to handle the truth or a strong opinion I would not bother.

Please take the time to post clearly so we can answer quickly. All lowercase and multiple typos makes for a hard read. Thanks!

I always include them in my orders from Niagara. Most of them come in bags of 144 for around $3. Shipping cost clobbers you on small orders, whether it is from that auction site or others. If you are going to do much work on older bikes, its pretty easy to reach the $100 minimum free shipping mark with Niagara: chain, cable housing, bottle cages, etc.

Wow - that *is* cheap! I wonder what grade they are - I'm guessing 300 or 1000 if they're anything like the ones LBSes sell on cards.

Not quite.

Small (1/8"); pedal, freewheel and freehub bearing balls
Small-medium (5/32") Recent Campy hubs
Medium: (3/16") Shimano and most other front hubs
Large (1/4") Shimano and most other rear hubs and cup-and-cone bottom brackets.
