"Si3N4 SIN balls 3mm" is that a ceramic ball bearing? It comes up as a ball bearing on Amazon that is a silicon ceramic. It looks fine to me but I don't know if that works.
I read that it is a modified version of SIC with higher tolerance to thermal shock when used in industrial applications. I found a thread on here selling them as terp balls so I thought it would be good to go.
