3.the best price


1. It has rolling sealed bearing structure. The cylinder rolling element is placed within the groove
of roller cone, thus enlarging the journal size and ensuring a better performance of roller bit.
2. The secondary surface of thrust bearing of roller bit has been handled with antifriction and
hardening treatment so as to decrease the frictional force of bit for protecting its hardening
resistance.
3. The roller bit uses new type lubricating grease which can bear the high temperature and boasts abrasion resistance.
4. The full rubber oil reservoir uses limitable differential pressure and can prevent drilling fluid
from entering lubricating system so as to provide qualified lubrication for bearing system
1. Elastomer (Rubber) Sealed Roller Bearing Bit
Cutting Structure The wear
resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces
for steel tooth 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 capability
and bearing life.
Sealed Bearing Structure 1.Abrasion resistance and seizure resistance of the bearing are improved.
2.Premium O-ring, Optimal seal compression and curved seal structure can enhance the seal performance.
