High Quality Silicon Nitride Ceramic Balls For Bearing
Silicon Nitride Ceramic Balls (Si3N4) ceramic high strength, good wear resistance, high stiffness, corrosion resistance, high temperature, suitable for high temperature structural materials. Comparing the three types of ceramic materials, Si3N4 integrated superior performance, has become the material of choice for ceramic bearings.

1. Low density: 3.2 g/cm3 with lightweight than most of other technical ceramics
2. Superior hardness, it's one of most hardest technical ceramic than others
3. Great wear resistance due to its exceptional hardness and self-lubricity
4. Low coefficient of thermal expansion and high thermal conductivity (20 W/m.k)
5. Great thermal shock resistance, it's up to 1000ºC under the special atmosphere
6. High mechanical strength and well resistance to impact than other advance ceramics
7. Heat & high-temperature resistance, The max. service temperature can be up to 1300ºC
8. Chemical and corrosion resistance, resistant to almost all inorganic acids and many organic acids
9. At the same time, Silicon nitride is a high-performance electrical insulation materia.
High speed bearing, high precision bearing; vacuum bearing; high/low temperature bearing, non-magnetic bearing, high precision ball screw; Si3N4 ball can also be used as valve ball and metering ball in chemical pump, high-temperature pump, metering pump. Si3N4 ball can also be used in linear slider for high temperature and corrosion resistance.
