I would not buy used bearings either. I'm seeing only new ones on eBay. Semi affordable. But they don't have dust shields on either side. Probably because they may get installed back to back or face to face. It's an enclosed motor, but FOD is most likely circulated from day one of manufacture.I would not buy any "used" bearings for a grinder spindle, without a money back guarantee.
And then, only if I was willing to waste the time to receive, check and return the bearings.
Why would someone be selling a used, matched pair of angular contact bearings?
Easier to find a full set of hens teeth.
Not sure how to proceed until reviewing the results of a survey.
I'll work more on this tomorrow, I need to pull the 6303 bearing off and check that bearing land.
That's a good idea to do quadrants and runout tests on the various critical features.
It's evident to me they didn't do this spindle as one setup.
