Linear guides and ball screws are two types of motion transmission components commonly used in mechanical systems. They have some differences in structure and function. 1. Structural differences: - Linear guide rail: Linear guide rail system usually consists of guide rail and guide rail slider. The guide rail is a linear guide rail that has high hardness and precision and can provide stable linear motion. The guide rail slider slides on the guide rail to achieve smooth linear motion. - Ball screw: The ball screw system consists of a screw and a ball nut. The screw is a helical rod-shaped element with threads on its surface. The ball nut is a part that fits on the screw and contains a set of balls inside. As the screw rotates, the balls push the ball nut in linear motion along the screw. 2. Functional differences: - Linear guide rail: Linear guide rail system has high stiffness, high precision and high repeatability of positioning accuracy, and can provide smooth and accurate linear motion. It is suitable for applications requiring high speed, high precision, high load and long stroke, such as machine tools, automation equipment and CNC systems. - Ball screw: The ball screw system achieves linear transmission through the motion friction between the balls and the screw. It has the characteristics of high efficiency, high stiffness and high precision, and is suitable for applications requiring high-precision linear motion, such as laser printers, robots, lifting platforms and CNC machine tools. In general, linear guides are more suitable for linear motion applications that require high stiffness and high precision, while ball screws are suitable for linear transmission applications that require high precision. The choice of transmission method should be determined based on specific application requirements. View our products to find the model that suits you. We support customization.

1. The transmission efficiency is different. The transmission efficiency of the ball screw is as high as 90~96%, while the transmission efficiency of the ordinary screw is about 26~46%. That is to say, under the same size of complexity, the ball screw can use a smaller driving power, which can effectively reduce production costs, reduce losses, and increase more benefits for the enterprise. 2. The transmission speed is different. The ball screw is rolling friction, and the ordinary screw is sliding friction. When the transmission is running, the temperature rise of the former is much lower than that of the latter. The ball screw can undertake high-speed transmission tasks. 3. The precision is different. The friction coefficient of the ball screw can be 0, but the ordinary screw directly increases the force at both ends of the sample through linear motion, so it has a certain sliding friction coefficient. Compared with the ball screw, the precision and efficiency are relatively low. 4. The service life is different. The surface friction of the ball rolling friction is small. Under the premise of reasonable operation of various cleaning and maintenance, the service life of the ball screw is longer than that of the ordinary screw. 5. Difference in self-locking property. Ball screws have almost no self-locking property and have reversibility of transmission; while ordinary screws have self-locking property. 6. Difference in economic efficiency. Ball screws are more complicated than ordinary screws, but they are also better, so the price of ball screws is a little higher than that of ordinary screws. In general, ball screws and ordinary screws have their own advantages and disadvantages, but ball screws are better than ordinary screws in terms of transmission efficiency, transmission speed, accuracy, load, life, etc., so they are more suitable for use in linear slide modules.
