Silicon nitride (Si3N4) ceramic balls are formed from a new material suitable for applications where high speeds, high loads and extreme temperatures are factors. The long life and the need for minimal lubrication make this material suitable for extreme applications. Silicon nitride is a non-magentic, non-porous, non-corrosive, and lighter than steel material. Silicon nitride balls are harder than steel, allowing them to withstand the harshest environments. Ceramic balls are virtually frictionless because they are non-porous, which gives them the ability to spin faster than steel balls.
Si3N4 Silicon Nitride Ceramic Balls
1. Material
Si3N4
2. Specifications
