6 1/2 inch IADC 537
Rubber Sealed Bearing TCI tricone Rock bit
Bearing Structure:
High precision journal bearing with two thrust faces.Balls lock the cone.Hard faced head bearing surface.Cone bearing inlaid with friction-reducing alloy and then silver plated.Abrasion resistance and seizure resistance of the bearing are improved.
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 reliability.
Product Application:
It can high WOB inthe conventional drilling.It is suitable for various of formations by matching cutting structure with different tooth shape,tooth density and tooth exposure height.
How to choose a model
IADC | Rock formation | WOB (KN/mm) | PRM(r/min) |
417/427/437 | Low compressive strength, high drill-ability and extremely soft formation, like shale, clay, sandstone,etc. | 0.35~0.90 | 140~70 |
447 | Low compressive strength, high drill-ability and soft formation, like shale, clay, sandstone, soft limestone, salt rock, plaster etc. | 0.37~1.00 | 140~60 |
517 | Low compressive strength, high drill-ability and soft formation, like shale, clay, sandstone, soft limestone, salt rock, etc. | 0.37~1.05 | 120~50 |
527 | Soft formation with low compressive, like Low compressive strength, high drill-ability and soft formation, like shale, clay, sandstone, soft limestone, salt rock, anhydrite etc. | 0.35~1.05 | 120~50 |
537/547 | Low compressive strength, medium hard formation with hard abrasive interlayer, like Hard shale, anhydrite, soft limestone, sandstone, dolomite with mezzanine, etc. | 0.50~1.05 | 110~40 |
617/627 | High compressive strength, medium hard and thick hard interlayer, like hard shale, limestone, sandstone, dolomite, etc. | 0.50~1.05 | 80~40 |
637/737 | High compressive strength, medium hard and high abrasive formation, like limestone, dolomite, sandstone, chert, etc. | 0.7~1.20 | 70~40 |
