Characteristics
1. The strength and wear resistance of inserts are improve by using carbide inserts with high strength and high wear resistance.
2. 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.
3. The service life of the bearing is further extended by adopting harder and more wear resistant material for thrust bearing.
4. This series oil well rock bit use sealed roller bearing structure. With rollers arranged in grooves recessed in the cone body, the size of the bearing journal is increased.
6. Thrust bearing surfaces are hard faced and treated with friction reducing technology.
7. Rotary drill bits use journal bearing. Hard faced head bearing surface. Cone bearing inlaid with friction reducing alloy and then silver-plated. The load capacity and seizure resistance of the bearing is greatly improve.
