The SFU series ball screw is one of the most widely used solutions for CNC machines, automation equipment, and precision motion systems. Models such as SFU1605, SFU1610, SFU2005, and SFU2505 are selected according to required load, speed, accuracy, and installation space.<\/p>\n

SFU Ball Screw Size Chart Overview<\/h2>\n

A ball screw is a mechanical transmission component that converts rotary motion into linear motion through recirculating ball bearings.<\/p>\n

Compared with a traditional lead screw, a ball screw uses rolling contact instead of sliding friction. This design provides:<\/p>\n

    \n
  1. Higher efficiency<\/li>\n
  2. Lower friction<\/li>\n
  3. Better repeatability<\/li>\n
  4. Higher accuracy<\/li>\n
  5. Longer service life<\/li>\n<\/ol>\n

    In CNC applications, the ball screw works together with:<\/p>\n

      \n
    1. Linearf\u00fchrung<\/li>\n
    2. Servomotor<\/li>\n
    3. Stepper motor<\/li>\n
    4. Steuerger\u00e4t<\/li>\n<\/ol>\n

      to create a complete motion control system.<\/p>\n

      What Is an SFU Ball Screw?<\/h2>\n

      An SFU ball screw consists of two main parts:<\/p>\n

        \n
      1. Screw shaft<\/li>\n
      2. Kugelmutter<\/li>\n<\/ol>\n

        Inside the nut, precision steel balls circulate through a return system.<\/p>\n

        The screw shaft contains a specially machined groove where the balls move.<\/p>\n

        When the screw rotates:<\/p>\n

          \n
        1. The screw shaft creates rotary movement.<\/li>\n
        2. The ball bearings transfer force through rolling contact.<\/li>\n
        3. The nut moves along the shaft.<\/li>\n
        4. Rotary motion becomes linear movement.<\/li>\n<\/ol>\n

          This mechanism allows the ball screw system to achieve precise positioning with low friction.<\/p>\n

          Components of an SFU Ball Screw and Nut System<\/h2>\n

          A complete ball screw and nut assembly usually includes:<\/p>\n\n\n\n\n\n\n\n\n
          Component<\/td>\nFunction<\/td>\n<\/tr>\n
          Screw shaft<\/td>\nProvides precision movement path<\/td>\n<\/tr>\n
          Kugelmutter<\/td>\nTransfers rotary motion into linear movement<\/td>\n<\/tr>\n
          Ball bearings<\/td>\nReduce friction<\/td>\n<\/tr>\n
          Return system<\/td>\nAllows balls to recirculate<\/td>\n<\/tr>\n
          Support bearing<\/td>\nSupports shaft rotation<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

          The quality of each component affects:<\/p>\n

            \n
          1. Accuracy<\/li>\n
          2. Rigidity<\/li>\n
          3. Noise level<\/li>\n
          4. Nutzungsdauer<\/li>\n<\/ol>\n

            For CNC machine builders, selecting a complete ball screw assembly is often more efficient than matching separate parts.<\/p>\n

            Why Are SFU Ball Screws Popular for CNC Machines?<\/h2>\n

            The popularity of the CNC ball screw comes from its ability to provide precise motion control.<\/p>\n

            Compared with traditional screw systems, ball screws offer:<\/p>\n

            Hoher Wirkungsgrad<\/strong><\/p>\n

            Because rolling contact replaces sliding contact, friction is significantly reduced.<\/p>\n

            This means:<\/p>\n

              \n
            1. Less energy loss<\/li>\n
            2. Lower heat generation<\/li>\n
            3. Better operational efficiency<\/li>\n<\/ol>\n

              High Precision<\/strong><\/p>\n

              For CNC equipment, positioning accuracy is critical.<\/p>\n

              A high precision ball screw<\/a><\/strong><\/span> provides:<\/p>\n

                \n
              1. Stable positioning<\/li>\n
              2. Repeatable movement<\/li>\n
              3. Accurate machining results<\/li>\n<\/ol>\n
