Product Features of Ceramic Bearings-zirconium oxide ball bearing

Zirconium oxide ball bearing has the characteristics of anti-magnetic and electric insulation, wear and corrosion resistance, oil-free self-lubrication, high temperature and cold resistance, etc., and can be used in extremely harsh environments and special working conditions. Rings and rolling elements are made of zirconia (ZrO2) ceramics, and cages are made of polytetrafluoroethylene (PTFE) as a standard configuration. Generally, glass fiber reinforced nylon 66 (RPA66-25), special engineering plastics (PEEK, PI), stainless steel (AISISUS316), brass (Cu), etc.

Product Features
1. Corrosion-resistant medium acid, medium alkali, can also be used in seawater
2. High temperature resistance, the strength and hardness of zirconia all-ceramics are almost unchanged at 600 °C
3. Non-magnetic, insulating, can also be used in a magnetic field, non-conductive
4. Light weight, 1/2 lighter than ordinary bearings, and its density is 6.00g/cm3
5. High rigidity, high hardness, its hardness is 1/2 times higher than that of bearing steel, and the elastic modulus is 210Gpa
6. High-speed rotation, the weight of the rotating body (ball) is light, and the centrifugal force is small when rotating
7. The linear expansion coefficient of zirconium oxide ball bearing is 10.5×10-6/K
8. The self-lubricating properties of zirconium oxide ball bearing can solve the pollution caused by the lubricating medium and the inconvenience of adding

Field of application
Semiconductor, PDP, LCD manufacturing equipment, electroplating equipment, synthetic fiber manufacturing equipment, optical film equipment, various heat treatment furnaces, vacuum equipment, etc. and in various harsh environments.
