Silicon nitride (Si3N4) ceramic balls are made from a new material for applications requiring high loads, high speeds and extreme temperatures. Long life and minimal lubrication requirements make this material suitable for extreme applications. Silicon nitride is a non-porous, non-magnetic, non-corrosive material that is lighter than steel. Silicon nitride balls are harder than steel and can withstand the harshest environments. Ceramic balls have almost no friction because they are non-porous, which allows them to spin faster than steel balls. At 800°C, the strength and hardness are almost unchanged, and its density is 3.20g/cm3, which is almost 1/3 of the weight of bearing steel, so the centrifugal force is small when rotating. High-speed operation can be realized.
