Are bearing codes universal?
Not car related, I'm in the middle of rebuilding my mountain bike rear hub which has 'cartridge' bearings. Unfortunately I
can't buy direct from the hub manufacturer and the local bike shops are providing poor service, so I'm trying to get the right bits direct
from a bearing supplier.
They're marked up on the dust covers as 6001 and 6002 (they are two different sizes), are these codes universal - I.e. can I just source some
6001/6002 bearings elsewhere and safely assume they'll be the same dimensions?

I don't know about the codes, but I did think it was fairly simple to take the relevant measurements (or even the bearing itself) to a bearing
supplier and get a suitable replacement?

Yup. Those sizes are standard. Check for any other letters too as they denote any sheilding.
I use simplybearings and bearingbrothers.

IMH(old) O Yes, but with variations
Ie a 6001 will alwaysbe 12mm ID 28mm OD but you may get different specs for dust oil sealing etc

i take any bearings into my local bearing services they generally offer a better replacement, the last ones i got were a set of four for a german made
trailer they produced four bearings no problem then said you would be better with this other set but they are expensive a £16 a set of four! guess
his expensive and mine are way different

I've gone with the tip of SimplyBearings and, because I spent summer holidays factory in Barnsley packaging them up many years ago, bought some
Koyo ones! Hope they prove to be decent quality :-)

with rubber sealed bearing, it is helpful to remove the dust seal - prise off with tiny jewellers screwdriver - and pack with grease.
also you know that to press them in, you press on the outer race not on the inner. use a suitably size socket or the old bearing race.

This is something I read a lot. I think I know the source. I don't agree. Repacking.sealed bearings risks seal damage and gives you no added
protection over the (correct) amount of grease that the manufacturer knows is required for their bearing. If you go river riding, maybe, but not for
general use.
