LG steel tooth bits-Tricone/Rock bits
Cutting Sstructure
The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth suifaces for steel tooth bit.The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.
Gauge Structure
Multiple aguge 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 capability and bearing life.
Bearing Structure
High precision roller bearing with two thrust faces .Balls lock the cone .The leg bearing can get larger by
arranging the rollers in groove of the cone hole,so it can receive more WOB,and suitable for high RPM.Thrust faces hardfaced with wear resistant alloy.Abrasion resistance and seizure resistance of the bearing are improved.
Seal and Lubrication
Premium HNBR O-ring,optimal seal compression and curved seal structure can enhance seal performance.the pressure compensator system and advanced grease can greatly increase the lubricating reliability.
Product Application
It can receive higher WOB and faster rotary speed than conventional roller bearing bits .It is suitable for high RPM applications.
