Multiple gague protection with gauge trimmers on the heel andgauge inserts on the gauge surface of the cone,tungsten carbide inserts andhardfacing on the shirttail increases gauge holding capacity and bearing life.
High precision journal bearing with two thrust faces,Ballslock the cone.Hardfaced head bearing surface.Cone bearing inlaid withfriction-reducing alloy and then silver-plated.Abrasion resistance and seizureof the bearing are improved.and suitable for high rotary speed
Seal and Lubrication
The advanced metal seal package consists of two metal sealsand two elastic energizers.Compressed energizers ensure good contact being kepton two sealing surfaces of metal rings by elastic force,and achieves thebearing seal.In the drilling,metal seals are relatively dynamic,and theenergizers are static.This will improve the reliability and durability ofbearing seal.The pressure compensator system and advanced grease can greatlyincrease the lubricating reliability.
It is suitable for down hole motor and high speed applications
