Bearing Failures in Wind & EV Motors? Si₃N₄ Balls Deliver Maintenance-Free and Electrically Insulated Performance

2025-02-03
Latest company news about Bearing Failures in Wind & EV Motors? Si₃N₄ Balls Deliver Maintenance-Free and Electrically Insulated Performance

Si₃N₄ balls are now the standard material for hybrid and fully ceramic bearings used in EV traction motors, wind turbine generators, and high-speed industrial spindles. They provide complete electrical insulation, eliminating current leakage paths and protecting lubrication integrity.

Thanks to their low density and high stiffness, these bearings allow higher rotational speeds and lower vibration levels, directly improving energy efficiency. In long-term field use, the replacement interval was extended by 300–400%, while noise levels were reduced by 20%.
As industries shift toward electrified, maintenance-free systems, silicon nitride bearings are recognized globally as the ultimate solution for high-speed, high-voltage, and high-reliability rotating applications.
