Tungsten Carbide Radial Bearing

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.

TC Disc Bearing: Hard alloy covering rate reached to more than 80%. It has a longer life and more antifriction.

Performance:

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.

Tungsten Carbide Radial Bearings

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.

Tile TC Bearings

  • Most commonly used in mud lubricated drilling tools.
  • Tungsten carbide covers approximately 55% of surface area. (Can cover more depending upon tile configuration and placement)
  • Typical life expectancy: 300 – 400 hours. (Run life solely depends upon drilling environment, mud composition, bend settings, carbide configuration and quality)
  • Average hardness for the tungsten carbide is 70 HRC. (Different compositions are available at customers request)
  • Average hardness of substrate is 28-36 HRC. (Many material and heat treating options are available)
  • Common sizes available include but are not limited to: 2 1/8”, 2 3/8”, 2 7/8”, 3 3⁄4”, 4.75”, 5”, 6.25”, 6.50”, 6.75”, 7.75”, 8”, 9 5/8”, and 11 1⁄4”
  • Both imperial and metric units are available.

Grain Style TC Bearings

  • Average hardness of carbide grain matrix: > 70 HRC.
  • Average substrate body hardness: 28-36 HRC. (Different values provided upon customers request)
  • Common sizes available include but are not limited to: 2 1/8”, 2 3/8”, 2 7/8”, 3 3⁄4”, 4.75”, 5”, 6.25”, 6.50”, 6.75”, 7.75”, 8”, 9 5/8”, and 11 1⁄4”
  • Grain styles perform best in enclosed environments of oil. Under magnification it has been noted that oil accumulates in the areas where washand erosion of the matrix happen. This holds tiny pockets of oil, which helps in lubrication of the bearings.
  • Typical life expectancy: 300 – 400 hours (Run life solely depends upon drilling environment, mud composition, bend settings, carbide saturation and quality)
  • Tungsten Carbide layer can be applied in various thicknesses with our unique processing.

Round Button Style TC Bearings

  • Round TC tiles are configured so that there is no direct pathway for the fluid to wash or erode. This helps with keeping fluid flow through the bearing pack to a minimum as radial bearings act as a flow restrictor as well.
  • Configuration of buttons allow for more carbide per square inch > 70% surface area. (Buttons can be stacked much closer together)
  • Typical life expectancy: 300 – 400 hours. (Run life solely depends upon drilling environment, mud composition, bend settings, carbide saturation and quality)
  • Average hardness of TC Buttons: > 70 HRC
  • Average substrate body hardness: 28-36 HRC. (Many material and heat treating options are available)
  • Common sizes available include but are not limited to: 2 1/8”, 2 3/8”, 2 7/8”, 3 3⁄4”, 4.75”, 5”, 6.25”, 6.50”, 6.75”, 7.75”, 8”, 9 5/8”, and 11 1⁄4”

Hexagon Style TC Bearings

TC Radial Bearing For Mud lubricated Motors For the Oil Drilling industry

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

TC Radial Bearing For Mud lubricated Motors For the Oil Drilling industry

  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.
