What we do

A Problem-Solving Culture

US Synthetic Bearings makes long-lasting diamond bearings for process-fluid-lubricated applications, including those used in down-hole drilling tools. US Synthetic presses its own polycrystalline diamond (PCD) and finishes each part to exact specifications to give customers confidence that their high-performance product will hold up under extreme conditions.


Engineered for the most challenging environments

US Synthetic Bearings is a dedicated business division of US Synthetic -- a 30-year industry veteran and a leader in the development and production of polycrystalline diamond cutters (PDCs) for oil and gas exploration. US Synthetic and the Bearings division pride themselves on an uncompromising commitment to constant innovation, outstanding quality, and superior customer service, allowing our engineering teams to meet high performance standards and match the requirements of the world's most demanding oil exploration and development projects.
