High-Sensitivity, Environmentally Isolated Bearing Tester

A novel tool was developed that allows users to qualify small-diameter bearings before incorporating them into components. The High-Sensitivity, Environmentally Isolated Bearing Tester was developed to measure the coupled torsional loss resulting from rotation of the inner race of a small-diameter bearing. It is up to 20 times more sensitive than commercially available bearing testers, and comes with a suite of software that allows users to conduct testing based on what the bearing will experience in different applications.
