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 energineers. 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.
