Approved for public release; distribution unlimited ABSTRACT (Maximum 200 words) MoS 2 sputter-coated as well as uncoated (bare) angular-contact ball bearings were tested with various cage materials in a low-speed regime. Various self-lubricating polymers either "neat" or with additives and metallic cages were tested. The emphasis of this paper is to report on significant torque increases "torque bumps" observed during non-ball overlap, oscillatory motion for some race/cage combinations. In some race/cage combinations torque bumps can be minimized by proper run-in. No attempt was made to run the bearings to failure, although certain race/cage combinations did in fact fail before the end of test.
