The paper presents an analysis of the specific dynamic capacity of a planetary roller screw including random deviations of the thread pitch. Results are based on a statistical analysis of loads between the screw and the roller obtained for the accepted bar model to determine the load distribution. Furthermore, the finite element analysis has been applied to determine stiffness coefficients of the screw-roller and the roller-nut cooperation. The purpose of the following considerations is to assess a decrease in the specific dynamic capacity of the planetary roller screw depending on random deviations of the thread pitch.
