393.7mm IADC 637Gtricone bit(rubber seal bearing)
Structure features:
1, the sliding bearing form. Tooth palm bearing surface surfacing layer of hard alloy, cone bearing with reduced after welding together gold for silver, improve the bearing capacity and resistance to bite ability;
2, bearing type O sealing ring is wear-resistant, high temperature resistant high saturation NBR, increase the sealing ring section reduces the pressure seal, carefully designed sealing convex platform outside the improved seal reliability.
3, USES the steel ball or card lock reed cone way, card lock can endure high reed drilling pressure, steel ball to lock the can adapt to high speed.
4 the differential pressure and prevent drilling fluid restrictions in the lubricating system all rubber oil storage sac, for bearing system provides good lubrication guarantee.
5, 250 ° C temperature the high temperature, abrasion resistance of new grease.
6, set foot drill using high strength and high toughness carbide gear, optimize the design of the tooth row number, gear, toothy height and unique alloy tooth shape, give full play to the set feet high wear resistance and excellent bit of cutting ability. Ruler bit tooth face apply welding new wear-resistant materials, and to maintain the mechanical drill bit ruler speed at the same time, improve the drill bit cutting teeth life.
Product advantage:
HA series bit for O form rubber sealing sliding bearing drill bit, in a routine use can withstand high speed drilling of pressure, with different cutting structure, can adapt to a very soft and hard strata.
