Power Factory 12 1/4inch IADC537 Tricone Rock Bits

8. 5inch 215.9mm IADC537 Tricone Rock Bit For Water Oil Well Drilling

1)Rubber sealed 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.
Seal and Lubrication
The bearing seal is adapting the high quality HNBR O-ring. The best seal compression and the radial seal structure can enhance the seal performance. The compensation system and the high quality bit grease can limit pressure differential, and greatly increase the lubricating reliability.
2)Metal Sealed Bearing 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.

3) rubber seal bearing Bit
Air cooling roller bearing package.Balls lock the cone,which reduces the probability of cone-dropping to minimum.
