Material Cronidur30
ISO Standard: DIN 1.4108
Chemical formula: X30CrMoN15-1
Advantages: Finer structure, less heat generated, higher permissible contact pressure, much higher fatigue life reliability (10x compared with GCr15 in best case), better corrosion resistance and high temperature resistance
Material Ceramic Si3N4
Advantages: Excellent tribological properties, lower density to improve the bearing kinematics, lower coefficient of thermal expansion, no magnetism, high current insulation

Do you know how to figure out the concentricity of a ball bearing Spindle when it spins at high rpm?? I know cap gauge is a good approach ……. but you might have an better idea?
