The operating principle of a roller screw is to convert the sliding motion of the screw from the rotational motion of screw engagement to linear motion through the movement of the screw and precision screw between the nut. The theory of planetary roller screws was proposed as early as a hundred years ago. Due to the high difficulty in producing roller screws, which are key components known as three-dimensional gears, and the need to consider various complex factors such as friction coefficient, screw and screw load and force distribution, the structural design and processing threshold are high, and there are only a few manufacturers in the world that can mass produce them to this day.
