Description
Specification About Kingdream TCI Tricone Rock Roller Bit
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.
3.Steel teeth Tricone bits
1 This series tricone 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. O ring seal is made of the more wear resistance high saturated buna-N with the increased
seal section and precisely designed sealing flange in the cone sealing area increased the
reliability of the seal.
3. The bit bearing can be ball locked
4. For steel tooth bit, the tooth surface is hardfaced with new type of wear resistan
Material and thus extended working life of the cutting structure while still maintaining high ROP
