1.PDC thrust bearing is widely used in downhole dynamic drilling tools, it is with high hardness and longer life charateristics. It can be in operation at super high temperature (currently the highest temperature is 233℃）and it can hold higher axial load. One pair PDC thrust bearing includes upper ring and bottom ring,one piece PDC thrust bearing includes two part: tungsten carbide ring and PDC compact.PDC material friction coefficient is very low so that it can not be affected by chemical material.
2.PDC thrust bearing is made with standard brazing technology, its compact surface hardness is very high, the contact surface flatness of PDC compact is very low and difficult to manufacture. Few factories in China could overcome this problem.
3.With many times improvement Research and development, we use more advanced welding and grinding technology, has overcome the flatness problem of PDC compact contact surface, make the contact surface flatness less than 0.02mm so that strongly improved PDC thrust bearing service life. Our technology for manufacturing PDC thrust bearing has reached the international advanced level in the industry.

- Q:Characteristics of cross roller bearings
- 4, substantial savings in installation spaceThe size of the inner and outer ring cross roller bearing is miniature minimal, especially ultra-thin structure is small size close to the limit, and has high rigidity, so the most suitable for industrial robot joints or rotating parts, machining center of the rotary table, the robot rotating parts, precision rotary table, medical instrument IC, measuring equipment, manufacturing device widely used.5., high speed capacity6. reduce the shaft length and processing costs, thermal expansion leads to limited changes in geometric size7. 、 adopt nylon separator, low rotating inertia, low starting torque, easy to control angle division8., optimize pre tightening force, stiffness, guide roller running high accuracy9. carburizing steel provides excellent impact resistance and surface abrasion resistance
