GHJ series tri-cone rock bits with metal-sealing bearing system for oil well drilling.
Main structure features:
1. This series adopts non-isometry teeth placement in combination with optimized teeth height and shape.
2. Applying the world's latest sealing technology, metal face sealing ensures the bearing the bearing sealing is more efficient, and more suitable for drilling at high rotary speed and high tem-perature working condition.
3. New materl is applied on the part of gate protecting, and rducing the friction from oil well wall; improving quality of well wall, protecting the back of leg and seal.
4. Bit's bear is enhancedtreatment, and prolonging te bit working life, reducing the drilling cost.
