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.
Bearing structure
High precision journal bearing with two thrust faces.Balls lock the cone.Hardraced head bearing surface.Cone bearing inlaid with friction-reducing alloy and then silver-plated.Abrasion resistance and seizure resistance of the bearing are improved,and suitable for high rotary speed.
Seal and lubrication
The advanced metal seal package consists of two metal seals and two elastic energizers.Compressed energizers ensure good contact being kept on two sealing surfaces of metal rings by elastic force,and achieves the bearing seal.In the drilling,metal seals are relatively dynamic,and the energizers are static.This will improve the reliability and durability of bearing seal .The pressure compensator system and advanced grease can greatly increase the lubricating reliability.
