Advantage of Aluminium Oxide Al2O3 bearing ball


 

1.High temperature-resistant:100°C--1300°C.It can  been applied in kiln, plastic, steel and other equipments that can bear high temperature.
2.Corrosion-resistant: It can be used in strong acid, strong alkali, inorganic, organic salt, water, and other fields, such as electroplating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment, etc 
3.Electric-insulated: It can prevent arc damagebearings due to the high electric resistance, So it’s available in various of power equipment which need insulation. 
4.Vacuum: self-lubricating without oil

5. High speed:12000rpm--75000rpm
