Linear motion components are mechanical elements that convert rotary motion to linear motion or control and guide linear directional movement. Including ball screws, linear guides, cylinders, and actuators, these components enable precise positioning and feed operations in manufacturing equipment and automation machinery. Widely used in machine tool table feeds, robot arms, conveyor systems, and press machinery, they meet applications requiring high precision, high rigidity, and long service life. Clearly distinguished from rotary motion components, this is a specialized component group focused on linear motion transmission.
