AI that drew the diagram couldn't get it's neurons around how planetary screws in linear actuator should work. Here's an actual schematic: https://ae-pic-a1.aliexpress-media.com/kf/Sd3fe9841e4ed4871b86da2693f3f4293Q.jpg_720x720q75.jpg_.avif https://ae-pic-a1.aliexpress-media.com/kf/Sd3fe9841e4ed4871b... Why these screws are used instead of just threads? Because rolling friction is lower than sliding friction. You can use less or more of them trading friction for shock resistance.
