ABEC Silicon Nitride Ball Bearing HIP Si3N4 Balls Cage P6 4.763mm

6000 Ceramic Bearing Of HIP-Si3N4 races and balls + cage With P6/ABEC3 Precision

Description of 6000 Ceramic Bearing (Si3N4+):

1. Si3N4 races and balls: Are made of highly purified, submicron silicon nitride powder with an alpha phase of more than 92%, and is processed after HIP (Hot Isostatic Pressure) sintering technology. So the porosity, wear resistance, crushing value and fatigue contact life of HIP-Si3N4 have been greatly improved, which is the preferred material for ultra-high speed and high precision ceramic bearings.

2. cage: is made of tetrafluoroethylene polymerization of polymer compounds, with excellent chemical stability, corrosion resistance (is one of the best corrosion resistance materials in the world today, resistant to molten metal sodium and liquid fluorine, to acid and alkali and organic solvent), sealing, high lubrication, non-viscosity, electrical insulation and good anti-aging endurance, excellent temperature resistance (can work in +250℃ to -180℃ temperature for a long time). So the cage of this material fitted in bearings can still work in many extrem acid or alkali operating condition.

Performance advantages of 6000 Ceramic Bearing (Si3N4+):

The 6000 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 are wear-resistant, resistant to a variety of strong acid, strong alkali, salt corrosion (in addition to hydrofluoric acid, nitric acid), non-magnetic, non-conductive, have high insulation, high hardness high temperature resistance to about 1000 ℃ and high speed.

Application of 6000 Ceramic Bearing (Si3N4+) :

Silicon nitride bearings are suitable for high-speed, alternating load environment, so are usually use ashigh-speed spindle, electric spindle, CNC machine tool and motorized spindle bearings.
