Tungsten Carbide Insert Bits Tricone Roller Drill Bits RocK Roller Bits

 

Product specifications:

Tricone bits are available in new and used (re-tip and re-run) steel tooth and tungsten carbide insert, size from 3 3/8”(85.7mm)

to 26”(660.4mm) for use in all formations, with any bearing/seal type, and a wide range of additional custom features.

Tricone bit, are widely used in mining, oil well, water well, thermal drilling.

 

1, The bearings adopt high precision radial sliding two way thrust bearings,teeth bearing surface hardfacing of hard alloy layer,the roller bearing is made of alloy after welding to improve the carrying capacity and anti bite ability.
2, Using high-precision metal seal. The metal seal is sealed by a carefully designed metal seal ring as a bearing, and two highly resilient rubber seals are located in the palm and the seal area of the teeth as a static seal. The optimized seal compression ensures that the two metal rings The sealing surface always maintains good contact.
3, Steel ball locking cone, suitable for high speed.
4, The use of a limited pressure differential and to prevent the drilling fluid into the lubrication system of the whole rubber reservoir, to provide a good lubrication guarantee for the bearing system .
5, Using the new grease with high resistance to 250 degrees Celsius and anti-wear.
