Bearing ball (Si3N4)

The demand for ceramic balls is increasing in high-voltage EV motors!

The essential component for the electrification of automobiles is the motor, and a crucial part of the motor is the "bearing." Bearings reduce friction during rotation, allowing machines to operate with less energy, making them indispensable, especially in automotive and industrial machinery components. "Silicon nitride (Si3N4) ceramics" possess excellent mechanical properties such as high strength, high rigidity, and wear resistance, and are becoming increasingly popular as the material for bearing balls inside bearings. In particular, in the automotive and industrial machinery sectors, where "lightweight" and "electrolytic corrosion resistance" are required, there is a shift from steel balls to ceramic balls. Ceramic balls weigh less than half of steel balls, and high-insulating ceramic balls can prevent the occurrence of electrolytic corrosion damage, leading to a growing demand for ceramic balls in high-voltage EV motors. *For more details, please refer to the related links or feel free to contact us.*
