    G10 Silicon Nitride Ceramic Si3n4 Bearing Balls


    Description:


    Silicon nitride ceramic balls are precision ceramics sintered at high temperature in a non-oxidizing atmosphere. It has high strength, high wear resistance, high temperature resistance, corrosion resistance, acid and alkali resistance, and can be used for in seawater for a pretty long time with good electrical and magnetic insulation.


    Its density is only 3.20g/cm3 which is almost 1/3 of the weight of bearing steel, and this makes it has small eccentric force and can achieve high speed rotation. with the property of self-lubricating, it can be used under the environment where there is no lubricating medium and has high pollution, thus makes it the first choice for ceramic bearings and hybrid ceramic ball bearings.

    Advantages:

    1. Excellent high temperature strength.
    2. High breaking strength.
    3. excellent thermal shock-resistant.
    4. Resist to chemical corrosion.
    5. lubricating property.


    Application:


    Most ceramic balls are mounted in the bearing (high-speed bearing, high precision bearing, vacuum bearing, high/low-temperature bearing, nonmagnetic bearing, high precision ball screws) for the high technology industry, such as aerospace and national defense and etc. The ceramic balls can also be used for chemistry, metallurgy, medical treatment, food industry, oilfield, electronic engineering and etc.
