Gauge structure

Multiple gauge protection with trimmers on the heel of cone, tungsten carbide inserts and hard facing on the shirttail increases gauge holding capability and bearing life.

Bearing structure

High precision roller bearing with two thrust faces. Ball lock the cone. Thrust faces hardface with wear resistant alloy.Abrasion resistance and seizure resistance of the bearing are improved.

Seal and lubrication

Premium O-ring optimal. Seal compression and curred seal structure can enhance the seal performance. The 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. Limestone, dolomite, chert, firm sandstone, firm anhydrite and so on.
