[0002] Linear modules, also known as positioning modules, are a general term for devices capable of linear motion in the field of industrial automation. They are linear transmission devices, primarily of two types: one consisting of a ball screw and linear guide, and the other using a synchronous belt and pulley. Currently, linear modules, as high-precision transmission devices, are widely used in measurement, laser welding, laser cutting, small CNC machine tools, testing machines, and educational applications.
