The article deals with the failure mechanisms of the being under abnormal working conditions bearing knot that is between the aircraft engine rotors. The carried out power estimations and the analysis of electrophysical processes in the abovementioned bearing knot elements being under operation suggest the availability of some electrodynamic phenomena in its elements which may lead to their mechanical breakdown and further destruction under unfavorable operating conditions. For the purpose of increasing working reliability of the bearing it is advisable to conduct time estimation of the destruction process in its elements, to investigate space distribution of the residue magnetism in the element material after its stopping. On the base of these data it is necessary to correct the program of testing regulation and the list of the control parameters.
