The concept and design of ball screws can be traced back to the late 19th and early 20th centuries. During the industrial revolution, with the development of the machinery industry, people's demand for linear motion became more and more urgent. Previously, a combination of a screw and nut was commonly used to achieve linear motion, but friction and imprecise properties limited the accuracy and efficiency of the system. In this context, the ball screw was proposed and developed. Ball screws utilize the rolling relationship between the balls and the screw, resulting in low friction and precise linear motion. In the design of the ball screw, the balls are arranged on the threaded track of the screw. When the screw rotates, the balls roll on the track, converting the rotary motion into linear motion. The introduction of the ball screw has greatly improved the performance of the linear transmission system, increasing the efficiency, stiffness and precision of the transmission. They are widely used in various fields, such as machine tools, robots, automated production equipment, stage lighting systems, printing machinery, etc., providing these systems with high precision, high speed and reliable linear motion. With the continuous advancement of science and technology and manufacturing technology, the design and manufacture of ball screw are also continuously improved and optimized. Modern ball screws have achieved higher load capacity, longer service life, higher stiffness and better reliability. They have become essential key elements in many mechanical systems, providing important support for industrial automation and production.

The miniature ball screw is a transmission device with high precision and high stability, which has the following characteristics: 1.High precision: The miniature ball screw adopts the form of contact between the ball and the thread, so that its axial clearance is small, the transmission precision is high, and it can realize high-precision positioning and translational movement. 2.High stability: The balls of the miniature ball screw are in contact with the thread, and the friction coefficient is small, which can realize smooth movement, thereby reducing mechanical vibration and noise. 3.Long life: The friction surface of the miniature ball screw is made of high-strength material, which can withstand high stress and high load, and its few moving parts and low wear rate, so it has a long service life. 4.High transmission efficiency: The miniature ball screw has high transmission efficiency and can realize high-precision movement under high-speed and high-load conditions. 5.Easy maintenance and replacement: The micro ball screw has a perfect lubrication system, which can ensure its stable operation for a long time, and it is also easy to maintain and replace if there is a problem.
