Ceramic Grade 5 Bearings Advantages:
The coefficient of thermal expiation of Ceramic Bearing is 0.0000032/k but that of bearing steel is 0.00001/k nearly a 1:4 ratio. Therefore ceramic bearings are more stable and reliable in a temperature variance condition.
The Ceramic Grade 5 Bearing has double the hardness of bearing steel, and 1/3 modulus of elasticity larger than that of bearing steel, therefore the elastic deformation of Ceramic is small under an identical loading.
Ceramic Grade 5 Bearings can solve corrosion problems. Important to the Chemical industry, food industry and other highly contaminated applications.
The self lubricating qualities of ceramics lends itself to high vacuum applications where degassing from lubrications are a problem.
The non-magnetic advantages for electro-mechanical applications (and others) is another advantage of ceramic bearings. Metal flaking caused by wear from standard steel bearings is eliminated.
Affordable. The cost for hybrid bearings and now full ceramic bearings are now reasonably priced in comparison to specialty bearings normally used in severe applications.
Specialty Ceramic Materials are noted for their characters of high strength in high temperature, good wear ability, high rigidity, corrosion resistance, high temperature resistance, electrical insulation, non-magnetic, these characters qualify them for replacing steel to make bearing to meet the requirements in a severe condition where a steel bearing cannot withstand. Ceramic materials, which can be used in making bearings, include mainly silicon nitride (Si3N4), Zirconia (ZrO2), Silicon Carbide (Sic ) and so on.
