Feature
Journal bearing. Hardfaced head bearing surface. Inner hole of cone
is silver-plated. The load capacity and seizure resistance of the
bearing is greatly improved.
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.
All rubber compensator is used which can limit pressure
differential and prevent drilling fluid from entering the
lubrication system and this provides the bearing system with good
assurance of lubrication.High wear resistance and excellent cutting
ability of the insert bit are given full play by using carbide
compacts of high strength and high toughness in combination with
optimized compact numbers and rows,the exposure height and special
shaped compacts.
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
Application
Apply to Construction, Water Drilling, Mining, Horizontal
Directional Drilling, Geothermal and Environ-mental.
