TECH DATA OF YH-Y49-637 TRICONE SINGLE CUTTERS FOR PILING
PHOTOS OF REAL SHOT IN YINHAI FACTORY SEMI-FINISHED SINGLE CONES IN YINHAI WORKSHOP DESIGN CAPABILITY YINHAI TEAM WELCOME TO MAKE A VIDEO-CALL WITH US TO ONSPECT OUR FACTORY,AND LEARN OUR PRODUCTION LINE Advantages of YINHAI Single Roller Cone: Cutting design Reinforcing the comprehensive mechanical properties of cutting tooth by using high quality tungsten carbide inserts of new form Ula and new techniques of insert bit. Gauge Structure The multiple heel position with gauge trimming on the heel, tungsten carbide and hardfacing on the shirttail, strengthened spear point will enhance the gauge protection. Bearing High-tech design precision journal bearing with two thrust faces.Ball locked cone.Hardfaced head bearing surfaces.Cone bearing inlaid with friction reduced alloy and then silver-plated.for Abrasion resistance and seizure resistance of the bearing are improved, and suitable for high rotary speed. Sealing and Lubrication The advanced rubber seal package is made by rubber seal. The energizer and back-up ring will support the pushing force to make the two metal faces tightly contact.During the drilling, the rubber seals are relevant moving, and the energizers are static.This will increase the bearing seal reliability and durability.The compensation system and the high quality bit grease can limit pressure differential, and greatly increase the lubricating reliability.
