Product Description
Main structure features:
1. Floating bearing structure. The floating elements are made of new materials with high strength, high elasticity, high wear resistance and can endure high temperature, and bearing surface is treated with solid lubricant. This decreases the relative linear velocity of the bearing couple and reduces the temperature of the friction surfaces, which results in improved reliability and working life of the bearing under large WOB and high RPM conditions.
2. Precise metal face sealed. The two dynamic axial sealing rings of the sealing system are metal seals, and two highly elastic rubber energizers are seated separately in head and cone sealing areas functioning as static seals. Optimized sealing compression ensures good contact between the two metal sealing faces at all times.
3. Ball locked cone, suitable for high rotary speed.
4. All-rubber compensator is used to limit pressure differential and prevent drilling fluid from entering the lubrication system and this provides the bearing system with good assurance of lubrication.
5. New type of wear resistant grease that can sustain high temperature up to 250 degree is utilized.
6. High wear resistance and excellent cutting ability of the insert bit are given by using carbide compacts of high strength and high toughness in combination with optimized number of compacts and rows, compact exposure height and special shaped compacts. For steel tooth bit, the tooth surface is hardfaced with new type of wear resistant material and thus working life of the cutting structure is extended while high ROP is also maintained.
Product predominance: By combining advantages of both HJ and FA series bits, FJ series bits are ideal tools for drilling applications where high RPM and high WOB are needed. In addition to conventional formations, this series of bit can also drill effectively in non-homogeneous formations with stringers and higher impact vibrations.
Available sizes and types of FJ series tri-cone bits: FJ117, FJT127, FJ437, FJ447G, FJ517G, FJ537G, FJ617G, FJ637G, FJ737G, etc.
