Abstract
A steering shaft for a steering system of a motor vehicle, comprises an inner shaft mounted axially displaceably in a hollow shaft, wherein a rolling bearing having multiple metallic rolling elements, which are disposed axially in at least two rows, is disposed between the hollow shaft and the inner shaft. Previously known steering shafts cannot reliably present vibrations from being transmitted from the inner shaft to the hollow shaft. Therefore, the diameters of the metallic rolling elements decreases proceeding from the center of the rolling bearing toward the end faces thereof, wherein multiple mutually adjacent metallic rolling elements have identical and/or different diameters.
