Diamond powder bearings promoted to energy sector
Mar 8th, 2011
US Synthetic Bearings, a creator of synthetic diamond bearings for the energy industry, was selected to form part of the technology showcase at the US Department of Energy’s Advanced Research Projects Agency – Energy (ARPA-E) Energy Innovation Summit, joining companies such as Dow, Bosch, and Lockheed Martin.
The US Department of Energy has also given US Synthetic Bearings a grant to look at the advantages of diamond bearings in harsh underwater conditions for power generation.

Correlation of accelerated laboratory testing to actual
field performance is essential in successful development
of polycrystalline diamond cutters (PDCs) and diamond
bearing elements for down-hole applications. A
laboratory scale drill rig apparatus for the investigation
of diamond bearing and drag bit cutter performance
has recently been completed. The laboratory scale test
rig is capable of producing rotary speeds from 40 to
1500 rpm, normal forces up to 165 kN, torque up to
1900 Nm, and rates of penetration up to 67 m/hr. Drilling
tests to evaluate PCD cutters can be conducted using
a controlled normal force or controlled rate of
penetration. Test methods have been developed to
enable accurate comparisons of PCD inserts to be made,
typically in one day or less. PCD bit testing shows that
we can clearly differentiate cutting efficiency and wear
rates based upon changes in the material properties
of the PCD inserts. The test rig can also be utilised to
measure wear rates and frictional forces in diamond
thrust bearings. Full scale PCD bearing experiments
indicated that the bearings were capable of much higher
loading than previously thought. Correlation between
laboratory results and actual field performance will also
be discussed. Article by J. Lund, C. Cooley, J. Gonzalez
and T. Sexton.

US Synthetic Corporation (a provider of polycrystalline diamond cutters(PDCs) for oil and gas exploration) announced the availability of its radial bearing line that's based on synthetic diamond technology. Compared to tungsten-carbide technology, US Synthetic says its radial and thrust bearings extend bearing life by four to 10 times in the harshest real-world environments.

US Synthetic Bearings (USA, a division of Dover; NYSE: DOV) has launched the industry's first commercially viable lineup of radial bearings, based on synthetic diamond technology. Craig Cooley, US Synthetic Bearings Division General Manager, said: "Our radial bearings offer truly disruptive advances with longer life, reduced size, and increased lateral load-carrying capacity. A single installation can save many thousands of dollars in rig time."

Diamonds are not only "a girl's best friend." Soon they may be engineers' best friend too. US Synthetic Bearing takes advantage of its parent company's expertise with synthetic diamonds and applies that knowledge to radial thrust bearings to create a product that offers long life and low maintenance. Off-highway, oil and gas, and other industries benefit from these rugged bearings.
Design World's Leslie Langnau interviews Craig Cooley, General Manager of US Synthetic Bearings to find out more about Diamond Bearings, how they compare to more traditional bearings

Down-hole tools used for drilling oil and gas wells are subjected to harsh environments where abrasive fluids, high loads and speeds, and high temperatures can cause tool components, including thrust bearings, to quickly fail. This paper discusses the advantages that polycrystalline diamond can provide when used as a bearing material in down-hole tools. Laboratory test results are presented that can be used to help predict the performance of polycrystalline diamond bearings in these down-hole applications. Results from two types of tests are presented including tests that measure bearing capacity and those that evaluate diamond bearing wear rates. Bearing failures, generated during laboratory testing, are discussed. These failures are very similar to those observed in down-hole drilling tools and indicate that thermal damage to the polycrystalline diamond structure is the main cause of bearing failure. Bearing wear rates measured during laboratory testing show that polycrystalline diamond thrust bearings can provide a long-lasting bearing solution for down-hole drilling tools.
