Product Description Product Description4140 and 4340 alloy steel materials are most commonly used for the base material of our radial bearings. Custom steels are available upon customers request. Customer may also choose to use various tungsten carbide shape configurations including but not limited to tile, rounds, hexagon, rectangular, and grain style.Hexagon TC insert layouts are configured so that there is no direct pathway for the fluid to wash or erode. This helps with keeping fluid flow through the bearing pack to a minimum as radial bearings act as a flow restrictor as well.All TC radial bearings are well suited for high RPM, pressures, temperatures, corrosive and erosive environments.Hexagon TC inserts are capable of covering 70% + of bearing surface areas.Typical life expectancy: 300 - 400 hours. (Run life solely depends upon drilling environment, mud composition, bend settings, carbide saturation and quality)Average hardness of hexagon TC inserts: > 70 HRC.Average substrate body hardness: 28-36 HRC. (Many material and heat treating options are available)Common sizes available include but are not limited to: 2 1/8", 2 3/8", 2 7/8", 3 3?4", 4.75", 5", 6.25", 6.50", 6.75", 7.75", 8", 9 5/8", and 11 1?4" Tungsten carbide radial bearing is one of the important parts of the screw power drill for petroleum exploration drilling, it mainly bears the radial load generated by the driving shaft of the power drill during operation, and its quality performance is directly related to the life of the whole drill.Tungsten carbide bearing of our company adopts general high temperature furnace integral sintering process and sintering formula. Strictly control the quality of raw materials to ensure that the tungsten carbide tiles meet the standards and requirements. An alloy layer below tile and matrix provides a stress relief and crack arresting feature, and ensures fusion between the substrate and the tile.Advanced technology protective measures, sintered materials under high temperature not oxidation, surface purification activation, liquid solder infiltration is good, the sintering shrinkage layer, not only to completely eliminate the sintering defects such as shrinkage, porosity, and prevent the crack problems in the sintering process, sinter layer are combined with matrix and firm, be in harmony are an organic whole, without peeling phenomenon of impellers.Proprietary design eliminates catastrophic downhole radial bearing failure.Carbide tiles and matrix design ensures extended life compared to cladding of welded overlay designs.With the high strength and hardness of carbide tiles, there will be no peeling and cracking problems when use, still with high wear resistance, impact resistance and various corrosion resistance under bad working conditions, the service life is about 300-400 hours, it depend on drilling environment, mud composition, bend settings, carbide configuration and quality)Exquisite product appearance, the coverage of cemented carbide tiles ≥60%.The hardness of matrix can be adjusted in the range of 200 ~ 330HB as required.Tungsten carbide radial bearing grade as followed, we can build based on client's requirement.Carbide GradeCo(Wt %)Density(g/cm3)Hardness (HRA)TRS(≥N/mm2)JC11-C9.0-11.014.33-14.5388.6-90.22800JC15-C15.5-16.013.84-14.0485.6-87.22800JC15X14.7-15.313.85-14.15≥893000JC2018.7-19.113.55-13.75≥83.82800JC06X5.5-6.514.80-15.0591.5-93.52800JC087.5-8.514.65-14.85≥89.52500JC098.5-9.514.50-14.70≥892800JC10X9.5-10.514.30-14.6090.5-92.53000 ApplicationOil and Gas Industry: Tungsten carbide bearings are often used in drilling and pumping equipment, where they help reduce wear caused by the high friction of rotating parts in abrasive environments. They are particularly beneficial in downhole tools and high-pressure pumps.Mining and Drilling: In mining operations, where equipment is exposed to abrasive materials and extreme conditions, tungsten carbide bearings are used in drill bits, rock crushers, and other mining machinery to ensure extended service life and reliability.Aerospace: In the aerospace industry, tungsten carbide radial bearings are used in various components such as turbines, actuators, and fuel systems, where their high load capacity and ability to withstand high temperatures and pressures are critical.Heavy Machinery: In large industrial machinery, such as manufacturing equipment, turbines, and heavy-duty pumps, tungsten carbide bearings help reduce maintenance intervals and improve overall machine performance in high-stress, high-speed environments.Chemical and Pharmaceutical Industries: Tungsten carbide bearings are often used in pumps and mixers that handle corrosive or abrasive chemicals. The bearing's resistance to wear and corrosion helps keep equipment running efficiently over longer periods, even under challenging conditions.Automotive and Performance Engines: In high-performance or heavy-duty engines, tungsten carbide bearings may be used in turbochargers, transmissions, and superchargers, where durability and resistance to friction are vital for performance and longevity.
