Schaeffler's screw model series Schaeffler's screw products are rich in types, advanced in technology, and widely used. The following is a detailed introduction: **Ball screw:** Schaeffler's ball screw is widely used in the industrial field, such as in the steering mechanism, electric power steering system, electronic parking system and brake system of automobiles. It can realize the efficient conversion of rotational motion to linear motion, has high transmission efficiency and precision, and can meet the requirements of precision motion control in the automotive field and other fields. **Planetary roller screw:** Schaeffler's planetary roller screw technology is in a leading position, such as the planetary roller screw used in its new mechatronic rear-wheel steering system. The screw is developed based on Schaeffler's precision mechanical technology in the industrial field and has the advantages of high precision, high efficiency, high load capacity and long life. In automotive applications, it can significantly improve efficiency, reduce friction and shorten system response time, making vehicle control more precise. Schaeffler screws have a variety of model series, the following are some common ones: **INA KUE series:** Belongs to the ball screw series and is widely used in the industrial field. **INA KWE series:** It is also a model series of ball screws, suitable for a variety of mechanical transmission scenarios. Planetary roller screw: Schaeffler's planetary roller screw technology is relatively advanced, such as the planetary roller screw used in its new mechatronic rear-wheel steering system, which is developed based on Schaeffler's precision machinery technology in the industrial field and has the characteristics of high precision and high efficiency. In addition, Schaeffler's screw products may also have other specific models and specifications according to different application scenarios and customer needs. For example, in linear modules, specific models of screws may be used to achieve precise linear motion control, such as the screws used in the MLF52 series linear modules.
