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.
