摘要

The ball screw has a spindle nut (3) arranged on a threaded spindle (1), where the spindle nut together with the threaded spindle borders an endless ball channel (9) for endless circulation of balls (2). The ball channel has a load-section wound around a rotation axis of the ball screw in a screw-shaped manner and a return section endlessly connects the ends of the load section with each other. The threaded spindle is provided with a recess for accommodating an insert (6), where a return section is formed as groove at the inserts.
