Ceramic Bearing 6805 Of Si3N4 Races And Balls + Cage With P6/ABEC3 Precision

Description of Ceramic Bearing 6805:

Si3N4 races and balls: Are made of highly purified, submicron silicon nitride powder and is processed after HIP (Hot Isostatic Pressure) sintering technology. So the porosity, wear resistance, crushing value and fatigue contact life have been greatly improved.

cage: has resistance to many kinds of acid and alkali and high temperature resistance, Electrical insulation and good resistance to aging. So it's a ideal material for cages of ceramic bearings.

Performance advantages of Ceramic Bearing 6805:

Ceamic bearing in material of silicon nitride has a small volume density, light weight structure, resistance to dry friction, low coefficient of linear expansion, self-lubrication, high fatigue life. They have high hardness, wear-resistance, resistance to a variety of strong acid, strong alkali, salt corrosion (in addition to hydrofluoric acid, nitric acid), non-magnetic, non-conductive, high insulation, high temperature resistance to about 1000 ℃ and etcs.

Application of Ceramic Bearing 6805:

Because of the excellent properties of silicon nitride, All-Si3N4 bearings are suitable for high-speed, alternating load environment, so they are widely used as high-speed spindle, electric spindle, CNC machine tool and motorized spindle bearings.
