1. Roller bits for Mining and Rock Drilling
The strength and wear
resistance of inserts are improve
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 Tricon 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.

4.These types of bits have some common features,as follows
1.Force balanced,resist impact to the blade during high-speed drilling,to make bit work stable.
2.Plus wear knot section,reduce collion in the hugh-speed rotational vibration.
3.Patented matrix formulation,extended bit life.
4.Optimal hydraulic desigh,easy to move out the drill cuttings and cooling.
5.Equipped with back reaming teeth.
6.The cutter is high performance to increase the ability of anti-impact and anti-abrasive.
