Does anyone offer a ceramic bearing for the 4985 1650?

^^^I have commented on the 3 phase wires and how they contribute to heat from EMF at the end bell elsewhere on AF. Perhaps not on this thread until now, here.
Don't misunderstand me. Disagree if you will, that's fine. But understand my knowledge better. That's all.
The topic is bearings. Cerams and heat. Bearings contribute much when they are inferior or worn or are over lubed, ill maintained.
EMF is a constant. Other contributing heat can be addressed, i.e. bearings.

^^^ The geometry of the circuit conductors at the entry of the rear end bell (3 phase wires) creates the most inductance. It has to do with the magnetic permeability of nearby materials. Hence higher heat build up at the rear. Easily available info. I didn't make this up. And perhaps beyond the scope of this thread for sure. ?‍
