◎ Ball screw is an ideal product to convert rotary motion into linear motion or linear motion into rotary motion. ◎ Ball screw is composed of screw, nut and ball. Its function is to transform rotary motion into linear motion, which is the further extension and development of ball screw. The significance of this development is to change the rolling motion of bearings into sliding motion. Ball screw is widely used in various industrial equipment and precision instruments because of its low friction resistance. ◎ Ball screw is the most commonly used transmission element in machine tools and precision machinery. Its main function is to convert rotary motion into linear motion or torque into axial repetitive force, which has the characteristics of high precision, reversibility and high efficiency.

1, compared with the sliding screw pair, the driving torque is 1/3. Because there are many balls rolling between the screw shaft and the screw nut of the ball screw pair, higher movement efficiency can be obtained. Compared with the sliding screw pair in the past, the driving torque is below 1/3, that is, the power required to achieve the same motion result is 1/3 of that of the rolling screw pair. This is very helpful for saving electricity. 2. High-precision ball screw pairs are consistently produced by the world's highest-level mechanical equipment made in Japan, especially in grinding, assembly and inspection of factory environment in each process, and the accuracy is fully guaranteed due to the perfect quality management system. 3. Possibility of micro-feed Because the ball screw pair adopts ball motion, the starting torque is extremely small, and there will be no crawling phenomenon similar to sliding motion, which can ensure accurate micro-feed. 4. The ball screw pair with no side clearance and high rigidity can be preloaded, because preloading can make the axial clearance reach a negative value, and then obtain higher rigidity (when the ball screw is applied to mechanical devices, etc.). Due to the repulsive force of the ball, the rigidity of the female threaded part of the screw can be enhanced). 5. High-speed feeding is possible. Ball screw can realize high-speed feeding (movement) because of its high movement efficiency and low calorific value. ◎ Accuracy tolerance: P5 .P7-
