PDC Radial Bearing Used For Internal Drilling Tool Components To
Protect Critical Surfaces From Erosion
Polycrystalline Diamond (PCD) radial bearings are comprised of a
series of PCD inserts assembled (usually by brazing) in carrier
rings. A typical PCD radial bearing set includes a rotating and stationary bearing ring. These two
rings oppose each other with the PCD surface on the inside diameter
of one ring in direct contact with the PCD surface on the outside
diameter of the mating ring.
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
diameter.
We can make PDC Radial bearing and PDC Thrust bearing as your
specific drawings or samples.
·Highly resistant to abrasion, erosion, corrosion, and mechanical
failure
·Extremely resistant to chipping, cracking, and flaking which are
inherent problems in cladding or welded overlay processes
·High heat conductivity eliminates thermal cracking
·Proprietary design eliminates catastrophic downhole radial bearing
failure
·Carbide tile and matrix design ensures extended life compared to
cladding or welded overlay designs
·Inner and outer components can be reconditioned.
PDC Radial bearings support the radial and bending loads on the
drive shaft. To this end, we have developed a proprietary
hard-facing process for maximum protection against radial wear.
This has resulted in high performance figures of about 10-20 times
longer than figures recorded using typical tungsten carbide cladded
bearings.
