A device for the measurement of the influence of friction force on the wear characteristics of a material surface comprises a frame with a cover. A shaft is installed in the frame. A moveable element of a friction pair is fixed on the shaft. A holder of a pressed element of the friction pair and a clamp which applies a regulated load on the holder with the pressed friction element are installed in the cover. The holder of the pressed friction element is installed in a holder frame with first membranes which allow the motion only perpendicular to the axis of holder frame. The holder-frame is installed in the cover also with second membranes that allow it to move only in its axial direction. The system of the membranes damps the impact of inertial forces on the friction pair.
