FWIW, my Grade 3 7/32 IN-C SI3N4 BALL GRADE 3 ball got sufficiently damaged after 18 months of use that the motor could no longer turn the platter at 33 RPM.

I thought at first oil was the issue, but even after adding huge amounts of oil, the problem persisted.

I replaced the bearing with a spare and the problem went away.

hi all
i use an aluminium oxide bearing ball , i have had not problems with that , i was talking to werner who said the Black ceramic can micro crack , i tried to put a small pad of ptfe on top of the bearing shaft ,,but this never worked the way i wanted it too , I now use ZX1 super Lube in my bearing ,it has a friction reducer that really works,, it is thin enough to allow the pump action of the Archimedes screw to work ,, but still keep an eye on the bearing ,, also according to michell ceramic bearings may cause more static , i have not had this problem ,, but others have,,
