Foreign ball screws are mechanical components that convert rotary motion into linear motion. They consist of a threaded shaft (screw) and a nut with ball bearings that roll between the screw and nut as the screw rotates. This rolling action creates a smooth and efficient linear motion, making ball screws ideal for use in a variety of applications such as CNC machines, robotics, medical equipment, and aerospace technology. Foreign ball screws are manufactured by companies around the world, including Japan, Germany, the United States, and China.
