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.

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.

Features:

1. Corrosion-resistant, strong acid, strong alkali, and seawater can also be used.

2. High temperature resistance, the strength and hardness of silicon nitride ceramic balls are almost unchanged at 800°C. 3, non-magnetic, insulating, can also be used in the magnetic field, non-conductive.

4. Light in weight, 1/4 lighter than ordinary bearings, and its density is 3.20g/cm3.

5. High rigidity, high strength, its hardness is twice as high as that of bearings, and its elastic modulus is about 1/3 higher.

6. It rotates at high speed, the weight of the rotating body (ball) is light, and the centrifugation is small when rotating.

7.The linear expansion coefficient of silicon nitride ceramic ball is 3.2×10-6/K, which is almost 1/4 of bearing steel.

8. The self-lubricity of silicon nitride ceramic ball bearings can solve the pollution and inconvenience of adding lubricating medium.

9.Chemical resistance, mechanical strength, fracture toughness, low thermal conductivity. Application areas: composite bearings,mechanical seals, chemical pumps, nozzles, auto parts, heat exchanger parts, vacuum equipment, etc. and various harsh environments.

Applications:

Silicon nitride ceramic balls can be used in various bearings with performance requirements:

high-speed/ultra-high-speed bearings, high-precision bearings, vacuum bearings, high/low temperature bearings, non-magnetic bearings, high-precision ball screws; can also be used It is used as valve ball and measuring ball in chemical pump, high temperature pump and metering pump. Silicon nitride ceramic balls are generally assembled into hybrid bearings, which can be used in high-tech industries such as aviation, national defense and other industries, and can also be widely used in chemical, metallurgy, food, oil, electronics and other industries.
