MOSIONX lead screw It has many advantages, such as high efficiency, zero backlash, reversibility, high rigidity, and high lead accuracy. Compared with conventional ball screws, a ball screw is added between the screw and the nut. By replacing the traditional sliding friction transmission of the screw with rolling motion of balls, friction losses can be significantly reduced, thereby helping to maintain high efficiency and high precision.

　　1. High efficiency and good reversibility

　　Because the screw shaft and nut of the MOSIONX ball screw adopt point-contact rolling motion, their efficiency can exceed 90%. Consequently, the driving torque required is only one-third of that needed by conventional lead screws. This results in higher motion efficiency and greater energy savings. The mechanical efficiency of the MOSIONX ball screw is significantly higher than that of traditional lead screws.

　　2. Zero backlash and high rigidity

　　CNC machine tools, IT equipment, and semiconductor devices demand zero backlash and high smoothness from drive screws. MOSIONX ball screws employ preload to achieve high repeatability and high rigidity throughout the entire stroke of CNC machine tools. However, excessive preload can increase operating torque. The increased friction torque generates heat, which in turn shortens the service life.

　　3. Ensure high lead accuracy and high precision.

　　MOSIONX lead screws are manufactured using high-level mechanical equipment, ensuring high production accuracy. The precision grades of MOSIONX lead screws are produced in accordance with ISO, JIS, and DIN standards, and can also be customized to meet specific customer requirements. Precision laser measuring instruments are employed to guarantee the accuracy of MOSIONX lead screws; each ground MOSIONX lead screw is accompanied by a wire-guide accuracy table, ensuring 100% quality. Thanks to the adoption of ball motion, the MOSIONX lead screw pair exhibits extremely low starting torque, virtually eliminating the stick-slip phenomenon commonly associated with sliding motions, thereby enabling precise micro-feed movements.

　　4. Life Prediction

　　Unlike conventional lead screws, the lifespan of this screw depends on wear at the contact surfaces. The quality of MOSIONX lead screws hinges on material fatigue failure. To ensure the reliability of MOSIONX lead screws from Shangyin in terms of service life, stringent professional considerations have been applied throughout the design, material selection, heat treatment, and manufacturing processes. The service life of MOSIONX lead screws must take into account several safety factors, including design quality and manufacturing processes; however, the most critical factor is the dynamic load.

　　5. Low starting torque and good smoothness

　　Since traditional lead screws rely on metal-to-metal surface contact, a higher starting torque is required to overcome the static friction. However, MOSIONX ball screws operate via rolling contact between steel balls, requiring only a very small starting torque to overcome friction. By employing tooth profile design coefficients (profile factors) and specialized manufacturing techniques, we achieve precise tooth profiles. Shangyin uses tooth-profile measurement equipment to monitor the tooth profile at each production stage, ensuring that the torque falls within the specified range.

　　6. Short delivery time

　　Arrange the processes and inventory for MOSIONX lead screws at a rapid pace to achieve the goal of short delivery times.

　　7. Mute

　　Even under high-speed feed and heavy-load operations, high-quality machinery still requires low noise levels. Only through strict control of the lubrication system, meticulous gear design, precise assembly processes, and careful inspection of surface finish and dimensional accuracy can low noise be achieved.

　　8. Gapless, high rigidity

　　MOSIONX lead screws can be preloaded, as preloading can reduce the axial clearance to a negative value, thereby achieving higher rigidity.
