Zirconia (ZrO2) all-ceramic bearing has the characteristics of non-magnetic, electrical insulation, wear resistance, strong acid and alkali corrosion resistance, oil-free self-lubrication, high temperature and high cold resistance, etc., which can be used in extremely bad environment and special working conditions that steel bearings can not adapt to. With stainless steel cage or full ball, can be used in high temperature environment above 450℃. With PTFE or PEEK holder can be used in temperatures above 250℃.

Silicon nitride (Si3N4) all-ceramic bearing has all the characteristics of zirconia ceramic bearing, but also has light weight, high hardness, more wear resistance, more high temperature resistance and so on. It can be used for higher speed and load capacity, stronger acid and alkali chemical corrosion, and worse environment and special working conditions. In the case of full ball, it can be used in high temperature environment above 800℃. With stainless steel cage can be used for 450℃ and above. With PTFE or PEEK holder can be used in temperatures above 250℃.

Silicon carbide (SIC) all-ceramic bearings have excellent properties such as high hardness, good wear resistance, high thermal conductivity, low friction coefficient, strong oxidation resistance, good thermal stability and thermal shock resistance. Chemical resistance is the best of the several ceramics, especially hydrofluoric acid (HF) corrosion resistance. Temperature resistance is also the highest in several kinds of ceramics, with full ball, can be used in high temperature environment above 1100℃. With stainless steel cage can be used for 450℃ and above. With PTFE or PEEK holder can be used in temperatures above 250℃.Silicon carbide (SIC) all-ceramic bearings have excellent properties such as high hardness, good wear resistance, high thermal conductivity, low friction coefficient, strong oxidation resistance, good thermal stability and thermal shock resistance.
