The advantages of all-ceramic bearings over steel bearings are:

1, Higher temperatures: Ceramic materials maintain their mechanical properties at high temperatures and can therefore be used in high-temperature applications. Zirconia can be used at 750ºC and silicon nitride at 1050ºC;

2. Resistant to acid, alkali, and salt corrosion, so they can be used in chemical corrosive applications. In corrosive environments, the average life of all-ceramic bearings is more than 10 times that of steel bearings;

3, Better suited to temperature variations: Since the coefficient of thermal expansion of ceramics is smaller than that of steel, the clearance of ceramic bearings is less affected by temperature variations than that of steel bearings, thus enabling them to be used over a wider range of temperature fluctuations;

4, Better resistance to galling and seizing: This is because the coefficient of thermal expansion of ceramics is smaller than that of steel, which helps to reduce thermal deformation and thus improve galling resistance;

5, Oil-free operation: Ceramics are self-lubricating and can also be lubricated with a medium, so they can be used in high-vacuum applications where lubrication is inconvenient;

6, Can be used in the requirements of electrical insulation, no static electricity occasions: our production of ceramics is not conductive, no static electricity, will not produce steel bearings of the phenomenon of current ablation;

7, Can be used in magnetic environments: Ceramics are non-magnetic, so magnetic foreign objects or abrasive particles do not easily adhere to the grooves, reducing abrasive wear.
