Product Description TCI Bit/Roller Roller Bit/Cone Drill Bit/water/oil well drilling,sealed metal bearing1) Main Features 1. Cutting StructureThe durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit. 2. Gauge StructureMultiple gauge protection with gauge trimmers on heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life. 3. Bearing StructureHigh precision bearing with two thrust faces. Balls lock the cone.Hardface heard 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. 4. Seal and LubricationThe advanced metal seal package consists of two metal seats and two elastic energizers. Compressed energizers ensure good contact being kept on two sealing surfaces of metal rings by elastic force, and achieve the bearing seal. In the drilling, metal seal are relatively dynamic, and the energizers are static. This will improve the reliability and durability of bearing seal. The pressure compensator system and advanced grease can greatly increase the lubricating reliability. 2) Avaliable models Model116 117 12 6127 136 137 216 217 226 226 316 317 326 327 336 337 115 125 135 215 225 235 315 325 335 114 124 214 314 111 121 131 346 347IADC CODE417 427 437 517 527 537 617 627 637 737 837 832 415 425 435 445 525 625 635 416 427 436 446 447 516 526 537 547 516 536 535Available sizes:From 3 3/4'' to 26"larger sizes for hole opener bit ,reamer bitor tell me what you want, i will try to help youAdvantagefavourable price and good qualtityBearing type:sealed bearing and non-sealed bearingHJ(metal sealed journal bearing) HA (rubber sealed journal bearing)Formation or layersoft ,medium soft ,hard,medium hard,very hard formationApplicationpetroleum&gas ,water well ,mining and tectonic industries ,oil field, construction, geothermal, directional boring, and underground foundation workif you have any question,pls feel free to contact with meNO.TRICONE ROCK BIT SIZEREG.PIN APIinmm13 3/495.32 3/823 7/898.42 3/834 1/8104.82 3/844 1/41082 3/854 1/2114.32 3/864 5/8117.52 7/874 3/4120.72 7/884 7/8123.82 7/895 1/2139.73 1/2105 5/8142.93 1/2115 2/3143.93 1/2124 3/4146.13 1/2135 7/8149.23 1/2146152.43 1/2156 1/8155.63 1/2166 1/4158.83 1/2176 1/2165.13 1/2186 5/8168.33 1/2196 3/4171.53 1/2207 1/2190.54 1/2217 5/8193.74 1/2227 7/82004 1/2238 3/8212.74 1/2248 1/2215.94 1/2258 5/8219.14 1/2268 3/4222.34 1/2279 1/2241.36 5/8289 5/8244.56 5/8299 7/8250.86 5/83010 1/2266.76 5/83110 5/8269.96 5/83211279.46 5/83311 5/8295.36 5/83412304.86 5/83512 1/4311.26 5/83612 5/16312.76 5/83713 3/8314.36 5/83812 7/16315.96 5/83912 5/8320.76 5/84013 1/8333.46 5/84113 1/2342.96 5/84213 5/8346.16 5/84313 3/4349.36 5/84414 1/2368.37 5/84514 3/4374.77 5/84615 1/2393.77 5/84716406.47 5/84817 1/2444.57 5/84918 7/8479.47 5/850205087 5/85122558.87 5/85224609.67 5/85326660.47 5/85428711.27 5/855307627 5/83)Photos of Products Details5. we can provide more size Steel tooth (IADC)111, 121,131117,124,126,127,136,137 211,311216,217, 227...TCI(IADC)415,435, 417,437515,525,535,545, 517,527,537,547615,625,635,,617,627,637,737512,522,532,612,622,632,732...FAQQ: Are you a manufacturer or trading company?A: We are a specialized manufacturer.Q: How about the delivery terms?1.
