Laboratory: Sandia National Laboratories (Sandia)

Technology: High Sensitivity, Environmentally Isolated Bearing Tester

Opportunity: This patent-pending technology has been completed by Sandia and qualified to its readiness through testing and demonstration. Sandia is seeking to license this technology to interested parties.

Details: Developed to measure the coupled torsional loss that occurs from rotation of the inner race of a small-diameter bearing, Sandia’s High Sensitivity, Environmentally Isolated Bearing Tester allows users to qualify small-diameter bearings before incorporating them into components.

Benefits: This novel technology is 20 times more sensitive than current commercial bearing testers, enabling it to have extremely fine accuracy and high resolution. The technology also comes with a software suite that allows its users to conduct testing based on what the bearing will experience in different applications.

Applications: The High Sensitivity, Environmentally Isolated Bearing Tester is most applicable to small bearing manufacturers.
