A Ball Screw is a type of mechanical device which translates rotary motion to linear motion with as much as 98% efficiency. To do this, a ball screw uses a recirculating ball mechanism, ball bearings move along a threaded shaft between the screw shaft and the nut.

Ball screws are used extensively across modern industries where controlled linear motion is critical. Below are some of the most common application categories:
1. CNC Machines
Whether it’s milling, turning, grinding, or EDM machines, ball screws enable precise tool positioning and smooth axis motion. Their accuracy and stiffness allow high-speed machining with minimal error margins.
2. Semiconductor Equipment
In wafer handling and precision positioning platforms, ball screws contribute to micron-level accuracy while operating in cleanroom environments with low dust and noise.
3. Medical Devices
Imaging tables, surgical robots, and diagnostic equipment use ball screws for their smooth motion and positioning precision—vital for patient safety and comfort.
4. Automotive Industry
Ball screws assist in dynamic assembly lines, robotic welding arms, and quality control inspection systems requiring high-duty cycles and reliability.
5. Aerospace and Defense
Flight simulators, control systems, and satellite equipment utilize ball screws due to their precision, durability, and ability to function under extreme conditions.
6. Industrial Automation
Pick-and-place units, packaging machines, and robotic gantries benefit from the consistent performance and longevity of ball screw mechanisms.

Ball screw is the most commonly used transmission element in tool machinery and precision machinery. Its main function is to convert rotational motion into linear motion, or convert torque into axial repeated force. It also has the characteristics of high precision, reversibility and high efficiency.

Characteristics of ball screw transmission: The ball screw transmission mechanism uses the ball between the screw and the nut as an intermediate element, changing the sliding friction transmission between the screw and the nut into rolling friction transmission. The ball screw and nut are both equipped with arc-shaped spiral grooves. The two arc-shaped spiral grooves are combined to form a raceway. There are many balls installed in the raceway, so there is rolling friction between the screw and the nut. Ball retainers are installed at both ends of the spiral groove of the nut to block it, and there is a return pipe to allow the balls to roll out of the nut body from one end of the spiral groove, and then return to the other end of the raceway along this return pipe. In this way, when the ball screw rotates relative to the nut to perform linear motion feed transmission, the balls continuously roll in the spiral raceway.

As a precise and labor-saving transmission mechanism, it is widely used in ball screws of precision machine tools and CNC machine tools.
