Pretty sure on the r8 spindle it is 2MM207* in Fafnir

I've got a set of Fafnir's bought on ebay, waiting for time and
motivation to install. Box says 2MM207WI DUL, additional info says *100%
tested per ABMA STD 13, ABEC 9-MMV

There's a couple folks selling these and the Barden bearings on ebay.
Might do well to price shop. I don't recall what I paid, but it was a
lot less than list price in the MSC catalog.

ABEC 9? That sounds to me like a bearing for a surface grinder. If
you got it cheap, you got a real deal. If memory serves a mill
usually uses something like an ABEC 3 (Use caution here, It has been
something like 20 years since I checked up on bearings) and a table
saw would uses the common ABEC 1. Price goes way up in between.
