The Kuroda screw pair is a mechanical component composed of screws, nuts, balls, and other parts. Its function is to convert rotational motion into linear motion or linear motion into rotational motion. It is a further extension and development of traditional sliding screws. The profound significance of this development is similar to the changes brought by rolling bearings to sliding bearings. Due to its excellent friction characteristics, Kuroda screws are widely used in various industrial equipment, instruments, and precision CNC machine tools. Especially in recent years, the Kuroda screw, as a linear drive execution unit for CNC machine tools, has been widely used in the machine tool industry, greatly promoting the development of CNC in the machine tool industry. These all depend on its excellent characteristics in the following aspects: high transmission efficiency, high positioning accuracy, transmission reversibility, long service life, and good synchronization performance The Kuroda screw is an ideal product that converts rotary motion into linear motion, or converts linear motion into rotary motion.

The specialty of Kuroda lead screw
1. More energy-efficient
The driving torque is only one-third of that of the sliding screw pair, which has high motion efficiency and can save more electricity.
2. High precision guarantee
Kuroda screws are produced continuously by high-level mechanical equipment, with higher manufacturing accuracy.
3. Micro feed may
Due to the use of ball motion, the starting torque of the Kuroda screw is extremely small, and there will be no crawling phenomenon like sliding motion, ensuring precise micro feed.
4. No side clearance, high rigidity
The Kuroda screw can be preloaded, as preloading can cause the axial clearance to reach a negative value, resulting in higher rigidity.
5. High speed feed
Due to its high motion efficiency and low heat generation, the Kuroda screw can achieve high-speed feed (motion).
