The wear of thrust 51100 rolling bearings was investigated and their dissipative responses in a bench test rig were associated to their heating, elastic energy of mechanical vibration and Sound Pressure Level [dB], regarding two greases, both from the same supplier, being one with graphite and the other with Molybdenum Disulfide. The samples were commercially acquired and submitted to a normal load of 450±5N and 3100±30 CPM, determined after the screening tests. Four variables were measured: temperature [K], electrical power [W], global velocity vibration [mm/s] and Sound Pressure Level [dB]. After 106 cycles, the tracks were analyzed by Optical Microscopy. The bearings lubricated with the grease with graphite showed different responses in relation to the ones lubricated with MoS2 thrust bearings. The signal of the signatures and the damage morphology are presented and discussed.
