Abstract. The purpose of this research is to analyze the phenomena connected to a shaft supported by two roller bearings using the concept and theory of Jeffcott rotors, whose dynamic behavior at a given speed, can represent phenomena such as displacement side of the shaft, misalignment of the shaft and to bearing failure, among others. The studies are conducted comparing the accelerations of the theoretical model to the experimental model, whose physical model has a one degree of freedom SDOF.
