Tungsten carbide TC Radial bearings support the radial and bending loads on the drive shaft

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 34 size). Besides, 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, rectangular, and grain style.

Cladding Specifications Substrates Cladding can be applied to most alloy steels, carbon steels, precipitation hardened steels and stainless steels. Bearings can be heat-treated after cladding process to restore mechanical properties of steel.

Temperature Continuous operation at temperatures up to 1900° F (1038° C) with nominal performance impact. Able to withstand transients in excess of 2000° F (1093° C).

Chemical Resistance Compatible with all downhole chemicals, such as H2S, H2SO3, H2SO4, HCl, CL2, Salt, Water, Oil and Natural Gas.

Advantages:

1. Increased Bearing Life
Our exclusive cladding sustains tight tolerances and remains durable, even under extreme heat and stress.
2. Reduced Operational Costs
3. Improved Mud Motor Performance
Operators can push motors without damaging the bearings, permitting sharper turns, faster penetration and less drilling time.
4. Enhanced Drilling Accuracy
Reduced bearing wear means that design tolerances are maintained downhole, resulting in improved mud motor control and greater drilling accuracy.
5. Unsurpassed Quality Standards
Our radial bearings are designed and manufactured according to stringent quality standards that govern material selection, machining, infiltration brazing, surface finishing and packaging.

Features:
1. Use 100% tungsten carbide raw material
2. Stable chemical properties
3. Excellent performance and good wear / corrosion resistance
4. HIP sintering, good compactness
5. Blanks, high machining accuracy / precision
6. OEM customized sizes available
7. Factory’s offer
8. Strict products quality inspection
