Ball screws are used to convert rotary motion into linear motion. They consist of a spindle with a spiral groove and a ball nut that fits the groove. The balls in the nut roll along the groove on the spindle when the spindle is turned, causing the nut to move linearly.

Ball screws have several advantages compared to other types of linear drives. They can achieve very high precision and are therefore ideal for applications where accuracy is crucial. In addition, they are very rigid, which means they won’t bend or deform under load. A ball screw also has a long lifespan as the balls in the nut reduce friction and wear.

The many benefits also mean that ball screws are used in a wide range of applications such as CNC machines, 3D printers, robots, material handling machines, and medical devices.

In addition to these specific applications, ball screws can also be used in many other machines and devices where a mechanical drive with high precision, rigidity, longevity, and efficiency is needed.

The ball screws are made from high-rigidity materials that are intensively heat-treated and backed by years of experience in processing techniques. This has resulted in some of the most durable ball screws on the market. The high efficiency of ball screws is significantly better than conventional screws and the required torque is less than 30%. The ball screws are specially designed with a gothic arc groove profile that allows axial backlash to be reduced to zero at preload and smooth operation is possible. This allows both low torque and high stiffness to be achieved at the same time.
