摘要: An earth-boring bit has a mechanical face seal assembly with PCD faces. The bearing shaft cone rotatably mounted on the shaft. locates between and for sealing lubricant therein. includes at least one rigid ring having cemented carbide body an annular located it. mating may also be of material. contains binder that migrates into while is being formed. A binder-free region leached surface face.
