Zirconia Insert Bearings With Adapting Thread Of Customized Model
Material properties of ZrO2 (HIP sintered)
Zirconia bearing is 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.
