Structural Features
Tricone bit Cutting Structure
1. The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.
2. Tricone bit Gauge Structure
Multiple gauge protection with gauge trimmers on heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.
3. Tricone bit Sealed Bearing Structure and Lubrication
High precision bearing with two thrust faces. Balls lock the cone.Hardface heard bearing surface. Cone bearing inlaid with friction-reducing alloy. Abrasion resistance and seizure resistance of the bearing are improved and suitable for high rotary speed. Grease compensator to maintain pressure inside the bearing and improve lubrication.
4. Tricone bit Sealed Bearing Structure
API standard threads are turned with precision machining making them concentric to the gage rows for uniform loading on bearings.
