The lubrication device has a ball spindle and a screw nut. The ball spindle is spiral shaped and has a groove (11). A return channel (23) is provided and the nut (2) encloses an outer ring (41) bearing (4). Distinguishing between the outer ring (41) and the nut (2), is a sealed space (6) for lubricating oil, and the nut has markings (7) which allow oil to be inserted via a lubing channel (74) so that balls (3) can be lubricated.
