The advantages of ZrO2 full ceramic ball bearings as below:
Could be used at higher temperature. Ceramic maintains mechanical properties at high temperature, so full ceramic bearing can be used at elevated temperature.
Corrosion resistant. Full ceramic bearing are more suitable for chemical industry application.
More suitable for temperature-variation application. Because thermal expansion co-efficiency of ceramic are smaller than metal, so the change of clearance of full ceramic bearing is smaller than that of metal bearing.
More resistance to seizing due to smaller thermal expansion.
Could work under poor lubrication, because ceramics are self-lubrication. Full ceramic bearing could be used at high-vacuum environment.
Could be used as insulation bearing and can prevent Electrical Arcing because ceramics is not electrical conductor.
Could be used in magnetic environment because ceramics do not respond to magnetic forces.
Silicone Nitride is the best ceramic material used for the ceramic bearings.
1) It has the density 3.20g/cm3, and is only half weight of zirconia bearings.
2) More light means more speed.
3) Chemical resistant. Can work in various chemicals.
4) No need lubrication, clean, and can wash in the water.
5) Non-magnetic and insulation. Reliable working.
6) Without cage, Constant working in high temperature till 800 Centigrade.
7) Outstanding long time working in low temperature till -80 Centigrade.
