If there's no number on the bearing you should be able to take a few measurements:
Outside Diameter (overall diameter)
Inside diameter (the inner diameter that fits on the shaft)
Width
Type i.e. roller, ball, thrust etc etc
Let us know how you get on.

std sizes, your local bearing trader should have them in stock or be able to get them within a couple of days.
Are you going to do a 'how to guide' or this??

It was not water pump. put alternator back on same noise stripped down alternator very dry front bearing have taken bearings off and have sent for bearings .Total cost of bearings ? 12 let you no .
novocaine why pay for a exchange alternator at about ?95 when you can do it your self for about ? 12 ? bearings cheaper if you sent away for them on Ebay

If you've got a noisy alternator before spending lots of money try spraying a little WD40 onto the belt while its running, it won't slip. Spray it in the gap where the belt meets the pulleys. It wears off after a bit but at least you know your alternator is OK.

I found this which might be useful to people in future, though annoyingly, none of the images work anymore…
