Torque Characteristics of Solid Lubricated Precision Bearings during Oscillatory Motion.

Abstract

MoS2 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.
