The substrate of Tungsten Carbide Radial Bearing is stainless steel and soldering with Carbide Tile Insert on outside surface or internal surface. It is used as antifriction bearing for downhole motor. We have three different types for your choice. The size is customized based on customer’s drawings.                         

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. Good 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

Our Advantages:
1. 100% virgin material. 
2. Strict products quality inspection      
3.  Flexible production management with faster lead time.
4.  Customized OEM service based on customer's drawings or samples. 
5.  Factory's direct offer Competitive prices with 10-30% saved or more.
