In addition to their procedures, in the context of classifying new rolling bearings, manufacturers have at their disposal guidelines from relatively new ISO 15242 standards. The basis for such classification is most often the results of measurements of the RMS values of the bearing vibration velocity in three measurement bands. However, the basis for these guidelines was developed over 75 years ago and was included in the American patent for a rolling bearing testing device USP 2,468,648. The methods currently used in post-production testing of tapered roller bearings do not provide a fully correct classification of bearings. In addition, the testing devices currently used for this purpose enable the identification of manufacturing defects to a very limited extent. The plane of the RMS value of vibration accelerations aRMS - Rice frequency fR is a tool that enables simultaneous analysis in terms of amplitude (signal energy) and frequency (average process frequency). The aRMS - fR plane in the short-time perspective enables the identification of non-stationarity of machine operation, and in terms of average values it can be a tool for assessing their technical condition. The paper presents the concept of using the aRMS - fR plane, in terms of average values, for the classification of new tapered roller bearings.
