Metal-face sealed bearing TCI Bit
 
Cutting Structure
The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.
 
Gauge Structure
Multiple gauge protection with gauge trimmers on heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.
 
Sealed Bearing Structure: 
1. Abrasion resistance and seizure resistance of the bearing are improved and suitable for high rotary speed.
2. The advanced metal seal package will improve the reliability and durability of bearing seal.
 
Main Type Available Size:
6",6 1/2",7 1/2",8 1/2",9 1/2",9 5/8",9 7/8",12 1/4",17 1/2", etc.
 
HJ series bit for oil well drilling
 
Main structure features:
1. High precision journal bearing with two thrust faces. Head bearing surface is hardfaced. Cone bearing is inlaid with friction reducing alloy and silver-plated. The load capacity and seizure resistance of the bearing is greatly improved.
2. Precise metal face seal. 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 which can 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°C is utilized.
6. High wear resistance and excellent cutting ability of the insert bit are given by using carbide compacts with 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:
 
HJ series bit uses the most advanced sealing technology in the world, i.e. the metal face seal (MFS). It can perform consistently in high speed drilling applications, and is the ideal tool for drilling directional and horizontal wells. In comparison with conventional rubber O-ring sealed bits, the average working life (total drilling hours) of HJ series bit under the condition of the same operating parameters can be increased by 35%.
 
Available sizes and types of HJ series tri-cone bits:HJ117, HJ127, HJ137, HJ417, HJ437, HJ447G, HJ517G, HJ527G, HJ537G, HJ547G, HJ617G, HJ627G, HJ637G, HJ737G,etc.
