Thrust Bearings

In down-hole drilling tools, large thrust loads can result from drilling and from the hydraulic loading caused by drilling mud flowing through tool components. US Synthetic PCD bearings provide a high-performance alternative to conventional bearings. PCD bearings are virtually impervious to abrasive particles in the drilling mud that often cause ball bearings to wear out more quickly.

Steel Grades

Our engineering team works with each customer to develop the best material specification for each application. Considerations such as load requirements, method of bearing retention, process fluid abrasives and fluid flow characteristics all play into the bearing ring steel grade specification.

The majority of PCD bearing applications are satisfied using 17-4 PH 1150 stainless steel. This material exhibits good machinability, maintained hardness during the braze heating cycle and is corrosion resistant. Other steel grade options are available.
