TCI Teeth Elastomer sealed bearing tricone rock bit
Gauge Structure
Multiple gauge protection with gauge trimmers on the heel of cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.
Bearing Structure
High precision bearing with two thrust faces. Ball lock the 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
Premium O-ring, Optimal seal compression and curved seal structure can enhance the seal performance. The pressure compensator system and advanced grease can greatly increase the lubricating reliability.
Product Application
It can receive highWOB in the conventional drilling. It is suitable for various formations by matching cutting structure with different tooth shape, tooth density and tooth exposure height.
Recommended Drilling Parameter
Cutting Structure
The durability of premium tungsten carbide insert is improved with new formulas and new techniques for insert bit.
