Silicon nitride ceramic balls
High precision: The dimensional tolerance is ¡¾0.0005mm, which can be used in high standard fine environment.
Self-lubricating: It can solve the pollution and inconvenience caused by the lubricating medium, and it can come into contact with food.
Non-magnetic insulation: The indoor resistivity is as high as 1013 ohm cm, and it can conduct electricity when the temperature rises to 600 degrees Celsius.
Good corrosion resistance: It can be used in medium acid, medium alkali and seawater.
Features of Silicon Nitride Ceramic Balls
Compared with steel, silicon nitride ceramic balls are lighter in weight, smaller in friction coefficient, better in motion, and 50% larger in elastic modulus than steel. Not only that, the thermal expansion coefficient of silicon nitride is less than 25% of steel. It can maintain high strength and hardness before 1000 ¡Æ C, corrosion resistance, no rust, no magnetism, and can work under the condition of no oil lubrication. At 800¡ÆC, the strength and hardness are almost unchanged, the density is 3.20g/cm3, the weight is almost 1/3 of the bearing steel, and the centrifugal force is small during rotation, which can realize high-speed operation.
Silicon nitride ceramic balls are precision ceramic balls sintered at high temperature in a non-oxidizing atmosphere. They are ground and processed for a long time and can withstand high temperature of 1200¡ÆC.

Two options for multi-layer protection
Silicon nitride ceramic balls are resistant to high temperature of 1200¡ÆC, and zirconia ceramic balls are resistant to high temperature of 600¡ÆC.
Our shop sells zirconia ceramic balls and silicon nitride ceramic balls. Silicon nitride ceramic balls have higher hardness and stronger high temperature resistance. You can choose according
to your actual situation.
