●Product Introdution:
Silicon Nitride Ceramic Ball is the most ideal bearing ball for bearing applications, due to the excellent properties of silicon nitride ceramics, it has many irreplaceable advantages comparing to traditional steel materials, such as: high mechanical strength, low wear loss, good self-lubrication, low density, high corrosion resistance, good electrical insulation etc.
Therefore, Silicon Nitride Balls are mostly used for some harsh working conditions: high speed/super speed bearings, high precision bearings, bearings in vacuum, high/low temperature bearings.
Moreover, Silicon Nitride Ceramic Balls can also used as valve ball or measurement balls in chemical pumps/high temperature pumps/metdering pumps.
●Feature:
High Hardness and wear-resistant, Strong acid, alkali resistance, can also be used in Seawater, Nonmagnetic, electrical insulation, can also be used in magnetic field, Centrifugal force is small when rotating due to the low density, Coefficient of Thermal Expansion is only 1/4 of GCrls, can be used in high temperature etc.
