Believe me, I've sought matched pair and triple sets, you name it, including matching bore and ring diameters to my needs. All with little to no luck. The last time my bearing supplier ever let me go in the back room and pick the bearings I wanted was let me see... never. You find old shelf stock of matched pairs on ebay sometimes. Even Mori Seiki sent me universal ground the one time I went to them for what I think was a triple set. They were all taped together as a group, so that was close. :-) They even had a different ball compliment count. Go figure.
