PF Ceramic Ferrule
PF ceramic ferrule is designed for threaded stud, there are 7 sizes for choice: PF6, PF8, PF10, PF12, PF16, PF20, PF24.
PF ceramic ferrule’s main raw material is cordierite. And by molding, making the green body, calcining, etc. It is widely used for magnetic force floating railway engineer, building the bridge, building the railway, large power plant, plane depot that needs wide span.
