The introduced vibrodiagnostic system is used in all the stands of 1680 mill of «Zaporozhstal» works  for control of the technical condition of electric motor bearing supports, reducers and gear stands, as well as gearing. General information about the system is provided. The paper gives the first results of diagnostic analysis of vibration signals and examples of detection of initiating defects in bearings of the reducer of stands 3 and 8, which were confirmed by subsequent preventive repair operations. 3 Ref., 11 Fig.
