CuttingStructure

The durability of premiumtungsten carbide inserts is improved with new formulas and new techniques forinsert bit.

Gauge Structure

Multiple gauge protection withgauge trimmers on heel and gauge inserts on the gauge surface of the cone,tungsten carbide inserts and hardfacing on the shirttail increases gauge holdingcapability and bearing life.

BearingStructure

High precision bearing with twothrust faces. Balls lock the cone.Hardface heard bearing surface. Cone bearinginlaid with friction-reducing alloy and then silver-plated. Abrasion resistanceand seizure resistance of the bearing are improved and suitable for high rotaryspeed.

Sealand Lubrication

The advanced metal seal packageconsists of two metal seats and two elastic energizers. Compressed energizersensure good contact being kept on two sealing surfaces of metal rings by elasticforce, and achieve the bearing seal. In the drilling, metal seal are relativelydynamic, and the energizers are static. This will improve the reliability anddurability of bearing seal. The pressure compensator system and advanced greasecan greatly increase the lubricating reliability.

ProductApplication

It is suitable for downhole motorand high speed applications?
