Precision Silicon Nitride 1.984mm 3.969mm 3mm 3.175mm 6.35mm 12.7mm Zirconia zro2 Ceramic Balls bearing

Precision Silicon Nitride ball bearing:

Silicon nitride ceramics is a kind of inorganic material ceramics that does not shrink when sintering. Silicon nitride is very strong, especially hot-pressed silicon nitride, and is one of the hardest substances in the world. With high strength, low density, high temperature resistance and other properties. It is a good material for making bearings.
