roller bit

 FA series journal bearing tricone bit 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 and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increase gauge holding capacity and bearing life.

 

Bearing structure

High precision journal with two thrust faces, balls lock the cone. Hardfaced head bearing surface. Cone bearing inlaid with friction-reducing alloy and then silver-plated. Abrasion resistance and seizure of the bearing are improved, and suitable of high rotary speed.

 

Seal and lubrication

Premium HNBR O-ring, optimal seal compression and curve seal structure can enhance the seal performance. The pressure compensator system and advanced grease can greatly increase the lubrication reliability.

Product application

It can receive high WOB in the conventional drilling. It is suitable for various formations by matching cutting structure with different tooth shape, tooth density and tooth exposure height.
