6305 Zirconia Ceramic Bearings OF P6/ABEC3 To P4/ABEC7 Precision
Description of 6305 Zirconia Bearing (Full Ball):
Racas and balls 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, to which is the ordinary zirconia bearings incomparable.
Performance advantages of 6305 Zirconia Bearing (Full Ball):
A kind of special bearings through full grinding, with high precision and a variety of excellent performance, has a density and linear expansion coefficient close to that of metal steel shafts, high hardness Hv1280, wear resistance, resistance to various strong acids, strong alkalis, salt corrosion (except hydrofluoric acid), non-magnetic, non-conductive, high temperature resistance, high operating speed, impact resistance, small starting torque, resistance to dry friction, is one of the most widely used ceramic bearings
Application of 6305 Zirconia Bearing (Full Ball):
Because of the outstanding porperties of zirconia and teflon, the zieconia bearings are suitable for certain vibration and mild impact environment, such as chemical, antimagnetic, semiconductor, medium/low speed and corrosive working environment.
