Currently widely used methods of vibration diagnostics of bearings are intended mainly for quasi-stationary conditions of their operation. The proposed method for calculating the parameters of the shock pulse generated in radial ball bearings due to the presence of structural radial clearances is a further development of theoretical and methodological research on the scientific direction of vibration-pulse diagnosis in relation to the operational assessment of the  technical condition of the ball bearings of transmission units of mobile machinery operating under variable load-speed conditions. An example of calculation of shock pulse parameters in ball radial single-row bearings of series 307 is  given. The bearings are mounted on the shafts of the universal bench test box with open power flow.
