Hardfaced head bearing surface.Inne hole of ocne is silve-plated.The load capacity and seizure resistance of the bearing is greatly improved.O ring seal is mode of more wear resistant and high saturated buna-N with the increased seal section and precisely designed scaling flange in the cone sealing ares has increased the reliability of the seal.All rubber compensator is used which can limit pressure differential and prevent drilling fluid from entering the lubrication system and thi provides the bearing system with good assurance of lubrication.High weat resistance and excellent cutting ability pf the insert bit are given full play bu using carbide compacts of high strength and high toughness in comnination with optimized compact numbers and rows, the exposure height and special shaped compacts. For steel tooth tricone, the tooth surface is hard taced with new type of wear resistant material and thus has extended working life of the cutting structure while still maintaining high ROP. Tricone rock drilling bit Features Bearing StructureHigh precision journal bearing with two thrust faces. Ball locked cone. Hardfaced 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.Cutting StructureReinforcing the comprehensive mechanical properties of cutting tooth by using high quality tungsten carbide inserts of new formula and new techniques of insert bit.Gauge StructureThe multiple heel position with gauge trimmer on the heel, tungsten carbide and hardfacing on the shirttail, strengthened spear point will enhance the gauge protection. Overview of Tricone BitTricone bit is mainly used in drilling, exploration, petroleum and trenchless as pilot bit. According to cutting material, Tricone bit can be divided into TCI bit and Steel tooth Bit. TCI bit adopts high-strength and high-toughness hard alloy teeth, optimized design of tooth row number, tooth number, tooth exposure height, and unique alloy tooth shape, giving full play to TCI bit's high wear resistance and excellent cutting ability.New wear-resistant material is applied to weld the tooth surface of the Steel tooth bit, which can maintain the high penetration rate of the Steel tooth bit and improve the life of the cutting tooth of the bit.According to the type of bearing, the tricone rock bit can be further divided into metal seal bearing and rubber seal bearing.
