Silicon Nitride Ceramic has only about 40% of the density of bearing steel but is much harder giving greater wear resistance. This Ceramic bearings are also capable of higher speeds due to the lower centrifugal force generated by the ceramic balls. However, due to the lower elasticity of the balls, the contact area between the balls and the raceway is smaller which causes a higher contact pressure. This can cause the raceways to wear faster. The speed increase for ceramic bearings is approximately 30-40% with adequate lubrication. This ceramic bearings can also operate better with limited lubrication but running speed should be reduced. They are also less subject to ball skidding under high acceleration with a low load.

Deep groove geometry for supporting both radial and axial loads and high speeds

Silicon Nitride Ceramic for durability and resistance to corrosion and high temperatures

Note, Chrome steel housing with better spin performace than stainless steel housing, but worst on corrosion resistance.
