Roller bits for Oil Drilling well 1. This roller tricone bit for oil drilling use Sealed roller bearing structure or metal sealed bearing triconebit. With rollers arranged in grooves recessed in the cone body, the size of the bearing journal is increased. 2. Thrust bearing surfaces are hardfaced and treated with friction reducing technology. 3. Ball locked cone, suitable for high rotary speed. Weifang Far Eastern Machinery can supply most of IADC code as following:IADC code: 116 117 12 6127 136 137 216 217 226 226 316 317 326 327 336 337 115 125 135 215 225 235 315 325 417 427 437 517 527 537 617 627 637 737 837 832 415 425 435 445 525 625 635 416 427 436 446 447 The tricone bit size rang is from 3 3/8" to 26".
