Advantages of YINHAI Single Roller Cones:
Cutting Structure
Reinforcing the comprehensive mechanical properties of cutting tooth by using high quality tungsten carbide inserts of new form
ula and new techniques of insert bit.
 
Gauge Structure
The multiple heel position with gauge trimmer on the heel, tungsten carbide and hardfacing on the shirttail, strengthened spear point will enhance the gauge protection.
 

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.
