The rolling bearings used in modern rotor machines in the oil-and-gas sector are seen as crucial components. The accuracy of their production complies with the highest operational requirements. However, bearings are also the most probable cause of rotor machine failures. This can be attributed to the friction in support assemblies. This article considers the mathematical dependencies reflecting the dynamic processes occurring in rolling bearing during operation. It will help construct a modern test-range model for vibration-based diagnostics of bearing systems. The experiments with the practical use of this model showed a fault detection accuracy of 82-84%, which is a very good result.
