Full ceramic bearing of ZrO2 material has perfect property such as suitable for low and high temperatures, high load capacity, corrosion resistance, magnetic insulation and self-lubrication. Thus it suits for the specific circumstances which are not available for steel bearings and hybrid bearings. The rings and balls are made of ZrO2 ceramic material and the cage usually adopts PTFE material. And materials such as GRPA66-25, PEEK, PI, AISI SUS316, SUS304 stainless steel etc could also be used for the cage.
Full ceramic bearing of Al2O3 material uses 99% Al2O3 ceramic, its rolling parts use Al2O3 ceramic as well.
Full ceramic bearing of Si3N4 material has similar property as ZrO2 material, besides it has lower weigh, good wear resistance, higher hardness, and it can bear higher temperature than ZrO2 material.
Compared with the other 3 types of ceramic materials, full ceramic bearing of SiC material is more outstanding in these aspects: higher chemical corrosion resistance, better strength, higher hardness, higher wear resistance, lower frictional properties, and suitable for the highest temperature.
