Right. It's like pushing a nut along a screw by turning the screw. This article is about exotic screw/nut assemblies which have lower friction, longer life, and more strength than ordinary screws. The recirculating ball screw used for automobile steering is the classic of such mechanisms.[1] Both roller and ball screws substitute rolling for sliding, always a win against friction.
