Product description
Specifications 1)Corrosion resistant
2)60% lighter than steel
3)Lower friction coefficient,rolls more freely
4).High temperature resistant
1 high temp.,high electic insulation and nonmagnetic
2 low density,
which have been the primaryly choice of ceramic bearings,
1.high corrosion resistance,which means they can be also used in strong acid,strong alkali and sea water. 2 High temperature resistance. Si3N4 ceramic balls can still retain the strength and hardness even the temperture comes to 1100 °C. 3 Electrical insulation,non-magnetic,they can also be used in magnetic field. 4.Si3N4 ceramic balls have a low density of 3.20g/cm³,it is approximately 60% lighter than steel wheel balls, which extremly decrease the centrifugal force that act on the groove when there is a rotate speed on the deep groove. 5 High rigidity and high strength.Compared with bearing steel,Si3N4 ceramic is twice higher in hardness and half higher in elastic modulus value. 6 The coefficient of thermal expansion of Si3N4 is 3.2 * 10 -6/K, it is nearly 25% of the bearing steel,which leads to a good thermal shock resistance of Si3N4 ceramic. 7 The self-lubrication of Si3N4 ceramic ball bearings can helop to solve the contamination and incovenient adding ways that caused by lubricator,it can be usde in vacuum and high temperature conditions. 8 High resistance to chemical corrossion,high mechanial strength and low thermal conductivity. Application fields: High precision ceramic bearings,high temperature bearings,vacuum bearings, nonmagnetic bearings, chemical pump,high tempature pump,ceramic valve,measure ball.
