Radial Bearings

Our PDC radial bearings are designed to carry the radial, or side loads, in down-hole drilling tools. US Synthetic bearings offer a more abrasive resistant bearing with the potential to increase tool life, reliability, and side load carrying capacity than tungsten carbide alternatives.

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.
