Long and trouble-free operation of rolling bearings is largely dependent on their lubrication. Lubricants reduce the levels of vibration and noise generated by a running bearing. This is desirable during operation. Whereas, from the point of view of post-production diagnostics, which uses vibroacoustic (VA) signals to evaluate the quality of bearings, lubricants can lead to unwanted masking of manufacturing defects. This is due to the decrease in amplitude and/or the change in the spectral composition of vibrations. Studies on the influence of lubricants on bearing vibrations were carried out on a set of 10 new tapered roller bearings using 12 oils of different kinematic viscosity.The influence of oil viscosity on the level of vibrations generated by bearings and the nature of this relationship were determined. The sensitivity of selected measures of acceleration of bearing vibrations to changes in viscosity of the lubricant used was determined in this paper. On this basis, the premises concerning the criteria for selection of a lubricant for the purpose of post-production diagnostics of rolling bearings were specified. Appropriate lubricant parameters have been defined to guarantee the stability of the rolling bearing testing process and to reduce the masking of manufacturing defects in the VA signal.
