Mining Well Drilling Tricone Rock Bit 200mm Iadc 545 High Performance

1. Roller bits for Mining and Rock Drilling

The strength and wear resistance of inserts are improved
1. Roller bits for Mining and Rock Drilling
The strength and wear resistance of inserts are improve by using carbide inserts with high

strength and high wear resistance.
Surface of the high precision bearing heat treated by using advanced heat treatment process to

improve the load capacity and service life of the bearing.
The service life of the bearing is further extended by adopting harder and mort wear resistant

material for thrust bearing.
Preventing reflux structure has dual function, it can avoid air counterflow and dust entering into

bearing when the air-compressor stop working accidentally, and separate air and water

in order to avoid water entering into bearing when it works normally to prolong the life of bearing.

2. Roller bits for Oil Drilling

1. This series tricone bit use Sealed roller bearing structure. 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.
