The linear module was initially invented and used by Germans, and its widespread application worldwide has brought significant changes to the automation industry. Typically, linear modules come in various forms and offer greater flexibility and higher positioning accuracy compared to traditional transmission devices like linear guides and ball screws.

Common linear modules mainly fall into two categories: one is the ball screw drive, and the other is the synchronous belt drive. Each type of drive has its own advantages and disadvantages in terms of performance.

The main advantage of the ball screw drive method is its high precision, capable of achieving a repeatable positioning accuracy of 0.006mm. The horizontal load capacity of ball screw modules is similar to that of belt modules. Although the operating speed is generally slower than that of synchronous belts, it also depends on the selected screw pitch, motor, and module type. Maintenance of the screw is important during use. After moving a certain distance, it is necessary to clean the dirt and replace the grease in a timely manner.

The characteristic of the synchronous belt drive is its faster operating speed, typically reaching 1m—2m/s, with a travel distance of up to 3 meters. A disadvantage of the synchronous belt module is that ordinary belts require higher maintenance frequency, and the repeatable positioning accuracy is usually 0.1mm lower than that of ball screw modules. Therefore, customers can choose the appropriate transmission method based on their equipment requirements.
