S Series Elastomer Sealed Roller Bearing Tri-Cone Bit

Cutting Structure

Enhancing the wear-resistance of teeth with high-density premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit. Reinforcing the compressive mechanical properties of inserts by using premium tungsten carbide insert with new formula and new techniques for insert bit.

Gauge Structure

Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capabilities and seal protection.

Bearing Structure

High precision roller bearing with two thrust faces. Balls lock cone. Thrust faces hardfaced with friction reducing alloy. Abrasion resistance and seizure resistance of the bearing are improved.

Seal and Lubrication

Premium HNBT O-ring, best seal compression and radial seal structure can enhance the seal performance. The pressure compensator system and advanced grease can greatly increase the lubricating reliability.

Product Application

It is applicable for various formations, and achieve high rotating speed under low to medium WOB applications.
