Cutting Structure
The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit.The durability of premium tungsten carbide inserts is improved with newformulas and new techniques for insert bit.
Gauge Structure
Multiple gauge protection with gauge trimmers on the hell andgauge inserts on the gauge surface of the cone,tungsten carbide inserts and hardfacing on the shirttail increases gague holding capability and bearing life.
Bearing Structure
High precision roller bearing with two thrust faces,Ballk lock the cone,.The leg bearing can get larer by arraning the roller 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 resisitance of the bearing are inproved.
Sealand Lubrication
Premium HNBR O-ring,optimal seal compression and curved seal structure can enhance seal performance. The pressure compensator system and adwanced 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 POM applications.
