| Version G | Version LM |
In Version G (rising spindle) the spindle provides the linear motion. In this design the spindle moves axially through the jack nut. Rotation of the spindle must be prevented; usually by fixing the end of the spindle to the item being moved. | |
| In Version LM the spindle is axially fixed and linear motion is transmitted to the running nut by rotation of the spindle. The nut must be secured against rotation by fixing to the item or mechanism being moved. | |
