Elastomer Sealed Roller Bearing Bit
1 2023-11-17

26"(660.4mm) IADC115 & 17-1/2"(444.5mm) IADC135

Recommended Drilling Parameters (Elastomer Sealed Roller Bearing Bit)




(Bit Dia.)



Applicable Formations

Very soft formations with low compressive strength 

and high drillability, such asclay, mudstone, chalk, etc.


Soft to medium soft formations with low compressive strength and high drillability,such as medium soft shale, anhydrite, medium soft limestone, medium soft sandstone, soft formation with harder interbed, etc.

Note:The upper limits of WOB and RPM in above table should not be used simultaneously.


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 new formulas and new techniques for insert 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 roller bearing with two thrust faces. Balls lock the cone. 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 the seal performance. The

pressure compensator system and advanced grease can greatly increase the lubricating reliability.

Product Application

It is suitable for various formations, and achieves high RPM under low to medium WOB application.
