Ball screws are ideal products for converting rotary motion into linear motion, or converting linear motion into rotary motion.
Ball screw is the most commonly used transmission component in tool machinery and precision machinery. Its main function is to convert rotational motion into linear motion or torque into axial repetitive force, while also possessing the characteristics of high precision, reversibility, and high efficiency. Due to its low frictional resistance, ball screws are widely used in various industrial equipment and precision instruments.
A ball screw consists of a screw, nut, steel ball, pre press plate, reverser, and dust collector. Its function is to convert rotational motion into linear motion

Characteristics and advantages of ball screw

1. Low friction loss and high transmission efficiency
Due to the rolling motion of many balls between the screw shaft and screw nut of the ball screw pair, high motion efficiency can be achieved. Compared with the past sliding screw pair, the driving torque reaches less than 1/3, which means that the power required to achieve the same motion result is 1/3 of using a sliding screw pair. It is very helpful in terms of power saving.
2. High precision
Ball screw pairs are generally produced using the world's highest level of mechanical equipment, especially in terms of factory environment for grinding, assembly, and inspection processes. Temperature and humidity are strictly controlled, and precision is fully guaranteed due to a sound quality management system.
3. High speed feed and micro feed may
Due to the use of ball motion, the starting torque of the ball screw pair is extremely small, and there will be no crawling phenomenon like sliding motion, ensuring precise micro feed.
4. High axial stiffness
Ball screw pairs can be preloaded, as preloading can cause the axial clearance to reach negative values, resulting in higher rigidity (by applying preloading to the balls inside the ball screw, in practical applications such as mechanical devices, the repulsive force of the balls can enhance the rigidity of the female part).
5. Cannot self lock and has reversible transmission capability
