Thanks all. Hold my hand here… is it better to work out all the sizes/quantity I need and order that way or go for a kit?
As per earlier post… lots of people saying XYZ bearing supplier are reliable… but they pretty much all are (99% of their revenue is engineering companies not us consumers)… most of them supply bearings from many manufacturers…
For frame bearings you almost definitely want specific high load/low rotation which means cageless inside… these are variously called MAXFILL or FULL COMPLIMENT it means they get bigger/more balls in… you almost certainly want sealed (last 2 letters of bearing code .. eg RS2 means both sides sealed.
and stainless
Then you need to choose brand (SKF/INA/Enduro etc) …
All your current bearings should have a code on them (printed on the seal or your manufacturer website) N,N,NN,AA (type you will want 6), grade, bore and section (RS/RS2).
Some places do specific bike kits, others you just search for the bearing ..prices are all usually very competitive so just choose the supplier that has the ones you need.
I’ve got a blind bearing puller kit so no worries doing the replacement myself
You usually need a drift to push them in… you can use a socket (or the old bearings will be the exact right size)… it should contact the OUTER ring not the inner … sometimes I use a threaded bar.. sometimes I just stick it in the bench vice with suitable padding… (depending on the bearing and how easy either is).
