PDC Mud Motor Radial Bearing Radial Tungsten Carbide Bearings

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).

Polycrystalline Diamond (PDC) radial bearings are comprised of a series of PDC inserts assembled (usually by brazing) in carrier rings. A typical PDC radial bearing set includes a rotating and stationary bearing ring. These two rings oppose each other with the PDC surface on the inside diameter of one ring in direct contact with the PDC surface on the outside diameter of the mating ring. PDC Bearings prides itself in its ability to precisely shape polycrystalline diamond. This has allowed Bearings to provide PDC radial bearings that have accurate diameters, tight clearance tolerances, and ultra-fine surface finishes.

Our PDC and TC (Tungsten carbide) Radial Bearing advatages are as the following:

1) Highly resistant to abrasion, erosion, corrosion, and mechanical failure

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 bearing failure

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.
