Abstract
A steering column for a motor vehicle may include a casing unit in which a steering spindle is mounted rotatably about a longitudinal axis that extends in a longitudinal direction. The casing unit has at least two casing tubes that have a polygonal cross section and are guided such that they can be adjusted relative to one another in the longitudinal direction. Rolling bodies that have a rolling body radius are arranged between the casing tubes such that the rolling bodies can roll in the longitudinal direction in at least three raceways that are distributed circumferentially. To increase rigidity and improve compactness, center points of the rolling bodies are at a radial spacing that is less than or equal to the rolling body radius from an envelope circle that circumscribes the casing tube, on which the rolling bodies can roll on the outside.
