* 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. * 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.
* Thrust bearing surfaces are hardfaced and treated with friction reducing technology.
*This series oil well rock bit use Journal bearing. Hardfaced 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 improved. 2 Introduction of oil well rock bit:
