This paper summarizes work performed by The Charles Stark Draper Laboratory, Inc. (CSDL) during a DOE/Sandia Laboratories sponsored contract (no. 07-6996) for the analysis and test of losses in ball bearings suitable for vehicular flywheel applications. Particular emphasis was placed on the CSDL full complement retainerless concept which prior research indicated had low loss and long life at high speed in a vacuum environment. Three sizes of standard bearings were modified to the full complement retainerless configuration. These modified bearings and several sets of standard retainer bearings were tested during the contract. Friction losses were obtained for a variety of radial and axial loads in vacuum and the results integrated into a performance prediction equation. The latter was formulated by combining the experimental data base with a theoretically derived model and allows the optimization of future ball bearing configurations for vehicular flywheel systems.
