Cover plate The component type of the ceramic bearingHybrid ceramic bearings --- Full ceramic bearings
ceramic bearings are actually hybrid ceramic bearings, which combine a steel race with ceramic ball bearings. Full ceramic bearings use ceramic races, which can be lighter and provide the lowest friction, Unsealed ceramic bearings can be used to upgrade components that don't use cartridge type bearings, like cup and cone hubs.
Ceramic Balls are usually made of following materials:
- Silicon Nitride (SiN4)
- Alumina Oxide (Al2O3)
- Zirconia Oxide (ZrO2)
- Silicon Carbide (SiC)
