Tricone Bit current location: Home > Tricone BitFHJ/HJT Series Tricone Bit

FHJ/HJTSeries
Metal Sealed Bearing Bit



FHJ/HJT Series Tricone Bit Diameter from 5 7/8-17 1/2 inch,IADC Code from 127 to 617.

Cutting Structure
Enhancing the wear-resistance of cutting tooth by welding new type of wear resistant material on the tooth surface of steel tooth bit. Reinforcing the comprehensive mechanical properties of cutting tooth by using high quality tungsten carbide inserts of new formula and new techniques of insert bit.
Bearing Structure
High precision journal bearing with two thrust faces. Ball locked cone. Hardfaced head bearing surface. Cone bearing inlaid with friction reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved, and suitable for high rotary speed.
Seal and Lubrication
The advanced metal seal package is composed by two metal seals and two elastic rubber energiners. The energizer and back-up ring will support the pushing force to make the two metal faces tightly contact. In the drilling, the metal seals are relevant moving, and the energizers are static. This will increase the bearing seal reliability and durability. The compensation system and the high quality bit grease can limit pressure differential, and greatly increase the lubricating reliability.
Product Predominance
It is applicable for downhole motor and high speed rotary application.
