The article is devoted to the analysis of the dynamic properties of the spindle assembly. We study elastic properties of supports and mathematical modeling of it. We calculated contact and elastic deformations in roller bearings. We also consider to simulation of contact-elastic displacements of a high-precision roller bearing. Based on a mathematical model, it is shown that the amplitude of oscillations at the spindle speed significantly affects to the quality of work. Due to the non-linearity of the bending coefficients and periodic changes of parameters we show non-linear damping of the rolling bearing.
