Abstract
Planetary roller gear drive with a spindle nut () that is arranged on a threaded spindle () and with a plurality of planets () that are arranged distributed around the periphery and are in rolling engagement with the threaded spindle () and the spindle nut (). The threaded spindle () has a plurality of helical windings wound around the spindle axis forming at least one thread groove (), and a sensor element () is arranged so that it cannot move in the axial direction relative to the spindle nut () and detects an axial displacement of the threaded spindle () and the spindle nut () relative to each other. The spindle nut () is supported so that it can rotate about the spindle axis on a housing () with the sensor element ().
