TCI 8-1/2 Inch 216mm Three Cone Tricone Roller Bit Oil Well Drilling In Blue
1.Cutting Structure
The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit.The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.
2.Bearing Structure
High precision journal bearing with two thrust faces.Balla lock the cone.Hardfaced head bearing surfaces.Cone bearing inlaid with friction-reducing alloy and then silver-plated.Abrasion resistance and seizure resistance of the bearing are improved.
3.Seal and Lubrication
Premium HNBR O-ring.optimal seal compression and curved seal structure can enhance the seal performance .The pressure compensator system and advanced grease can greatly increase the lubricating rellability.
