Bearing Testing

The bearings we are using for our testing platform have been failing.  The two bearing on the flywheel and the two bearings on the load bearing idler have broken.  We looked at several failed bearings under the microscope and determined that the failure was due to loading vice corrosion.  Ceramic bearings are looking more promising because they have a greater dynamic load maximum.  Worst case, we will have move to a larger bearing size.
