The paper presents application of a non-linear method (energy operator) to monitor the operation of a plain bearing. The possibility of using the energy operator to evaluate the energy of a simulated mechanical system was analysed. Then, an experiment was conducted in the laboratory environment which involved observation of oil vortexes. This allowed to show the possibility of using the energy operator as a descriptor of operating state of a hydrodynamic bearing.
