Re: Bearings for bottom bracket
There are very many bottom bracket ‘standards’ to choose from. You should state the make/model/year of your bike and ideally upload some useful photographs when you are able.

Simply take your bearings a bike shop and order a score or two the same size!Take the cups with you.

Depending on the system, e.g. External HollowTech or press fit, you can't normally change the bearings - just fit new. Square taper, normally can change.

Given the original question I think the only answer for the poster to find out is to take the bike to a shop for them to identify the type of bottom bracket (and indeed assess whether the current BB needs replacing)
From the top of my head there are about 5 or 6 different possibilities, and then varying sizes. And of course there are usually specialist tools required to remove and refit.

But if it's a traditional cup and cone BB, 22 x 1/4" balls, no higher than Grade 100.
