I took the bearings out of an Ames horizontal mill (1AM spindle) with the intent of replacing them - they're crunchy with decades of dried grease. I don't know that they're not pitted, but the visible parts look good.
They're common cheap bearings - New Departure 5209 double row and 6209 single row. Or they would be common and cheap except that they're high preload high precision (5209-X5).
They're still tight, but I can't get them smooth. The 6209 has a non-removeable shield to keep me from getting a brush or high pressure stream in, and the double row has a similar problem due to being double row.
I was going to try soaking them in lacquer thinner for a week in the hope that that would loosen the schmutz. If that fails then I was going to try hooking them up to some slow motor - something like a cheap hand-held mixer (like used for cakes) - and rotate them slowly for another week in kerosene or hydraulic fluid.
Anyone got any better ideas? I'd happily replace them, but I'm pretty sure they'll be well north of $100 each, so it's worth trying to save the old ones.
This is the overarm version of the Ames mill - it's the same bench-top size as the other Ames millers, but it has much beefier bearings than the non-overarm 1AM spindle version.
