1208 Silicon Nitride Ball Bearing 40x80x18mm PFA Cage P6 ABEC3 P4 ABEC7

Ceramic Bearing 1208CE of ZrO2 Races+Si3N4 Balls+PFA Cage OF P6/ABEC3 To P4/ABEC7 Precision

Description of Ceramic Bearing 1208CE:

1. Zirconia races: Are made by highly purified, sub-micron and after Y2O3-TZP stabled zirconia powder material, are processed by AP (Atmospheric Pressure) sintering and HIP (Hot Isostatic Pressure) sintering technology, so their porosity, wear resistance, impact resistance and resistance to fatigue contact life are greatly improved.

2. Silicon nitride 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 have been greatly improved.

3. PFA cage: PFA is a reformed material of Teflon, its melting cohesiveness is enhanced and the viscosity of the solution is decreased, while the properties are unchanged compared with that of PTFE. The resin can be directly processed by ordinary thermoplastic molding. 

Performance advantages of Ceramic Bearing 1208CE:

Combined the outstanding properties of zirconia and silicon nitride, the ceramic bearing 1208CE has good resistance to many kinds of corrosion, like strong acid and alkali corrosion,high temperature resistance, high fledural strength and excellent electric insulation and magnetic insulation.

Main application of Ceramic Bearing 1208CE:

Because of the outstanding porperties, the zieconia are suitable for chemical, antimagnetic, semiconductor, medium/low speed and corrosive working environment.
