Diamond Bearing Technology
Diamond bearings utilize Polycrystalline diamond (PCD) in their primary working surfaces. In general, bearings allow relative movement or rotation of two machine elements with respect to one another while minimizing heat generation and maintaining alignment between the respective machine elements.Diamond Bearing Technology
The performance of our bearings are the result of extensive Research and Development (R&D) conducted by US Synthetic engineering teams. Our research staff consists of professionals with advanced degrees in engineering, chemistry, and materials design. With more 30 years of diamond-engineering experience, US Synthetic has worked hard to deliver advanced PCD material and new and better ways of building custom bearings and components for our customers.
Our R&D department focuses on:
What is PCD?
Polycrystalline Diamond (PCD) is diamond grit that has been fused together under high-pressure, high-temperature conditions in the presence of a catalytic metal. The extreme hardness, wear resistance, and thermal conductivity of diamond make it an ideal material for bearings. Individual diamond crystals cleave quite easily when struck parallel to certain planes (the process used to facet diamond gemstones takes advantage of these relatively weak planes).Read More
Diamond as a Bearing Material
Polycrystalline diamond is known for its high thermal conductivity, low coefficient of friction, high toughness and other preferred physical and mechanical properties. Having a bearing material with high thermal conductivity reduces localized temperature extremes that lead to bearing degradation.Read More

Diamond Bearing Tribology Fundamentals
Tribology comes from the Greek word ‘tribos’ which means ‘rubbing’. It is a relatively new science that considers the friction, wear and lubrication at moving contacts. Diamond bearing tribology looks at the physics between two diamond surfaces moving relative to one another, most of the time in the presence of a lubricant.Read More
The PCD compacts used in our bearings are subjected to rigorous testing to ensure that they meet the needs of our customers. Impact and tensile strength, abrasion resistance, and thermal stability are evaluated in our state-of-the-art testing facility. Field tests are also conducted to validate laboratory data.Read More
