A couple of years back I was looking for this information when I was doing the 10ER that I gave my brother. I copied this from the yahoo site, sorry no date on it.
********************************************************************
-- Spindle/Quill Bearings:

Fafnir 202KDD6 - a 5/8" id x 3/32" thick bushing is needed with this bearing to position the front bearing collar correctly.
-- Pulley / Drive Sleeve bearings:
Sizes are .9843 ID (25 MM)
2.0472 OD (52 MM)
.5906 W (15 MM)
Original felt shielded Fafnir 205KLL2
good substitute double sheided Fafnir 205KDD
SKF 6205ZZ, 6205-2Z
and many other bearing manufacturers with same # as this is a standard bearing
A good source is
www.ebatmus.com, they carry both and the quill ones are particularly harder to find. I think the quill ones are about $10 per and the drive sleeve ones are about $15-$18 per bearing. So if you want/have to replace all four it can add up. Plus shipping's about $10.

It turned out it didn't need new bearings so I did not follow through getting any for the quill.
