PDC bearing introduction:
PDC and TC (Tungsten carbide) Radial Bearing is used as
antifriction bearing for downhole motor, which is widely used in
oilfield service companies & downhole motor factories. We have
three different types includes PDC radial bearing,PDC thrust
bearing,Tungsten Carbide Tile Bearing,Tungsten Carbide Grain
Bearing and Tungsten Carbide Disc Bearing,from size 54 to size 286
for your choice (a total of 14 size).
The specifications:φ124 xφ80 x H26 φ148 xφ91.5 x H26 PDC bearings
have high resistance to grinding and can operate at high
temperatures (currently at a maximum temperature of 233 ° C) and
can withstand large axial loads. PDC materials have a low friction
coefficient and are not affected by natural or mud chemicals
present in the well. Each pair of PDC thrust bearings consists of
an upper ring and a lower ring, and each bearing ring contains a
cemented carbide ring and a PDC cutter.
Our PDC and TC (Tungsten carbide) Radial Bearing advatages are as
1) Highly resistant to abrasion, erosion, corrosion, and mechanical
2) Extremely resistant to chipping, cracking, and flaking which are
inherent problems in cladding or welded overlay processes
3) High heat conductivity eliminates thermal cracking
4) Proprietary design eliminates catastrophic downhole radial
5) Carbide tile and matrix design ensures extended life compared to
cladding or welded overlay designs
6) Inner and outer components can be reconditioned.
7) The hardness of body surface can reach 30-37 HRC.
PDC Thrust bearing
Diamond bearing PDC Thrust bearing are widely used for turbo drills
and mud motors,we can supply the size from 1inch to 10inch in
diameter with good quality and best price.
1.Product Introduction of PDC Thrust bearing
PDC Thrust Bearing is widely used in turbo drills,mud motors and
other oil field applications. We have two different types includes
PDC radial bearing and PDC thrust bearing.Compared with tungsten
carbide bearing,The PDC bearing has longer working life,its life is
4-10 times longer than tungsten carbide bearing, meanwhile it can
also bear the increased load capacity.
2.Product Specification of PDC Thrust bearing
The bearings are available in size from 1inch to 10inch in
We can make PDC Radial bearing and PDC Thrust bearing as your
specific drawings or samples.
3.Production Feature and Application of PDC Thrust bearing
High wear resistance
High corrosion resistance
Longer service life
widely used in turbo drills, mud motors and many other oil field
