ProductDescription : Silicon nitride ceramic balls description:

Silicon Nitride (Si3N4) Ceramic Balls are formed from a new material suitable for applications where high loads, high speeds and extreme temperatures are factors. Long life and the need for minimal lubrication make this material appropriate for extreme applications. Silicon Nitride is non-porous, non-magnetic, noncorrosive, lighter than steel and, in ball form, is harder than steel. Because ceramic balls are non-porous they are virtually frictionless and are capable of spinning faster than steel balls.

Their characteristics are shown as below:

1. High corrosion resistance, which means they can be also used in strong acid, strong alkali and seawater.
2. High temperature resistance. Si3N4 ceramic balls remain the same strength and hardness even in 1100 ℃.
3. Electrical insulation, non-magnetic, they can also be used in magnetic domain.
4. Si3N4 ceramic balls have a low density of 3.26 g/cm3. It is approximately 60% lighter than steel balls, which extremely decrease the centrifugal force on the groove, in order to effectively reduce the wear and tear.
5. High rigidity and strength. Compared with bearing steel, Si3N4 ceramic is double higher in hardness and half higher in elastic modulus value.
6. The coefficient of thermal expansion of Si3N4 is 3.2×10-6/K. It is nearly 25% of the bearing steel, which leads to a good thermal shock resistance.
7. The self-lubrication of Si3N4 ceramic ball bearings can help to solve the contamination and inconvenient caused by lubricator, it can also be used in vacuum and high temperature conditions.
8. Low thermal conductivity.

Application domains:

high precise ceramic bearings, high temperature bearings, vacuum bearings, nonmagnetic bearings, chemical pumps, high temperature pumps, ceramic valve balls and measure balls.
