Yes Roadmasters is correct, it is properly called a screw drive and is used for all sorts of things in our niche hobby. For instance, they are commonly used on dump trucks to raise and lower the dump bed. They are also used to simulate hydraulic cylinders sometimes. They are usually too slow for that application. They work very well by the way. Many people actually prefer the screw drive compared to it's hydraulic counterpart for the dump truck application.
