Silicon nitride ceramic ballsΦ6.35

　　The essence of ceramic ball technology parameters

　　Main performance:

　　1: corrosion resistance, acid, alkali, can be used in sea water

　　2. High temperature resistant, zirconia ceramic ball at 700 ℃, strength and hardness is almost the same

　　3. No permeability, insulation, can also be used in magnetic field, and is not conductive

　　4. Light weight, lighter than general bearing bearing 1/2, its density is 6.00/3

　　5. High rigidity, high hardness, its hardness is higher than bearing steel 1/2 times, elastic modulus, 210

　　6. High inflation rate, thermal expansion rate is close to the metal, can be used with metal joint

　　7. The linear expansion coefficient of zirconia ceramic ball is 10.5 x 10-6 /

　　8. The zirconia ceramic ball self lubrication can solve the lubricating medium pollution and add to the inconvenience
