Tungsten Carbide Radial Bearing is used as antifriction bearing for downhole motor. We have three different types from size 54 to size 286 for your choice (a total of 14 size). Besides, we can design and manufacture related TC bearings according to the specification of customers:
We can supply three kinds TC radial bearings:
1.TC Tile Bearing
TC Tile Bearing:Hard alloy covering rate reach more than 55%
2. TC Grain Bearing
TC Grain Bearing: Hard holly ball with diameter of 0.7-1.2mm makes it more suitable for small and complicated TC.
3.TC Disc Bearing
TC Disc Bearing: Hard alloy covering rate reached to more than 80%. It has a longer life and more antifriction.
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.
4140 and 4340 alloy steel materials are most commonly used for the base material of our radial bearings. Custom steels are available upon customers request. Customer may also choose to use various tungsten carbide shape configurations including but not limited to rounds, hexagon, rectangular, and grain style.
Documentation such as material certifications as well as heat treatment and certificates of conformity can be supplied with each shipment. Part and traceability numbers can be included on every part for ease of tracking and verification.
Custom designs and prototypes are welcomed as well as small batch orders. Expedited deliveries can be arranged at time of order. Tungsten carbide bearings can also be ordered in either oversized or undersized configurations to fit customers special requirements.
The TC Radial Bearing mainly including the below types:
Bearing Bodies can have many various compositions some of the most common are: 4140, 4145, 4330V, or 4340. Custom configurations are available upon customers request. Standard bearing body material makeup is as follows:
After sintering and forced air cooling:
After thermal refinement:
High strength,long life inserted cemented carbide radial bearing is a proprietary product of our company (the largest and earliest company to manufacture radial bearings). Cemented carbide and special welding materials and cemented carbide additives regularly placed on the inner and outer surfaces of the radial bearing are fused with the based of the radial bearing through specific sinter processing. Its friction pair is featured by corrosion resistance, shock resistance, heavy load bearing and long life, and its appearance quality and technical indicators are superior than the similar products of other countries.
Expandable Liner Hanger
Expandable liner hanger is one kind of the application of expandable pipe technology in liner hanging. The technological principle of expandable liner hanger is different from slip type liner hanger. Using hydraulic or mechanical forces, the expansion cone pressurize expansion pipe inner of the upper casing pipe to form reliable sealing and support hanging weight of liner pipes. Compared with conventional hanger, the expandable liner hanger has a larger drift diameter, reliable annulus seal, large hang force and rotation ability, which is suitable for the lateral well, deviational well, horizontal well, deep well, extra-deep well, HTHP well and H2S well. It has an extensive market potential with great prospect.

Scope of Application
1.Vertical, inclined and horizontal wells: It can be suspended at any inclination between 00 and 900.
2.Deep, super-deep well : Lifting, lowering, rotation and circulation operations can be performed during tripping in to ensure proper installation of liner at the bottom .Hydraulic and mechanical forces can be used jointly to ensure proper expansion and installation of the hanger. Safely disposable in case of emergency.
3.HTHP wells : Metallic annulus sealing: sealling pressure: 35MPa. Operating temperature: 350 C.Service life: 20 years.
4.H2S-containing wells:H2S-proof expansion pipe and annulus sealing materials.
