1. Prevent current damage
Ceramic bearings are non-conductive and therefore suitable for applications such as DC and AC motors and generators where current is present.
2. Improve the speed performance
The density of the silicon nitride rolling elements is 60% lower than the density of the bearing steel rolling elements of the same size. The lighter weight means less inertia, which gives the bearing excellent performance during fast start and stop.
3. Long service life
The heat generated by friction in ceramic bearings is low, especially at high speeds, which helps to extend bearing life and extend relubrication intervals.
