◎Ball screw is an ideal product for converting rotary motion into linear motion, or converting linear motion into rotary motion. ◎Ball screw consists of screw, nut and balls. Its function is to convert rotational motion into linear motion, which is a further extension and development of ball screws. The important significance of this development is to change the bearing from rolling action to sliding action. Due to its small frictional resistance, ball screws are widely used in various industrial equipment and precision instruments. ◎The ball screw is the most commonly used transmission element in machine tools and precision machinery. Its main function is to convert rotational motion into linear motion, or convert torque into axial repetitive force. It also has high precision, reversibility and High efficiency features.

1. Compared with the sliding screw pair, the driving torque is 1/3. Because there are many connections between the screw shaft and the screw nut of the ball screw pair The balls are doing rolling motion, so they can achieve higher motion efficiency. Compared with the previous sliding screw pair, the driving torque is less than 1/3, that is, the power required to achieve the same motion result is 1/3 of the rolling screw pair. Very helpful in saving power. 2. High-precision guarantee The ball screw pair is continuously produced using the world's highest level of mechanical equipment made in Japan. Especially in the factory environment of grinding, assembly, and inspection of each process, the temperature and humidity are strictly controlled. , due to the perfect quality management system, accuracy is fully guaranteed. 3. Possibility of micro-feeding: Since the ball screw pair uses ball motion, the starting torque is extremely small, and there will be no crawling phenomenon like sliding motion, ensuring accurate micro-feeding. 4. The ball screw pair with no backlash and high rigidity can be pre-pressured. Because the pre-pressure can make the axial clearance reach a negative value, higher rigidity can be obtained (by pre-pressuring the balls in the ball screw, in actual use When used in mechanical devices, etc., the rigidity of the nut part can be enhanced due to the repulsive force of the balls). 5. High-speed feed possible: Ball screws can achieve high-speed feed (movement) due to their high movement efficiency and low heat generation. ◎Accuracy tolerance: P5 .P7 --
