    AI Overview
    Ball screw jacks with a traveling nut (often designated as Type R or Keyed for Traveling Nut, KFTN) feature a rotating screw and a moving ball nut that acts as the load attachment point. These high-efficiency jacks (often 90%+) offer high-speed, high-duty cycle, and precise linear movement, requiring a brake motor to hold position. 
    Key Features and Benefits 
    • Traveling Nut/Rotating Screw: The screw rotates while the nut travels linearly along the screw, allowing the motor to be located closer to the gearbox.
    • High Performance: Designed for fast travel speeds (
      20
      −200
       inches per minute) and high-duty cycles.
    • Efficiency: Ball screws are highly efficient, using less horsepower to move heavier loads, making them ideal for continuous operation.
    • Applications: Preferred for long travel lengths, industrial automation, material handling, and lifting or pulling tasks, as discussed in this guide to choosing a ball screw jack and on Lude Transmission.
    • Limitations: They are not self-locking; therefore, an external brake motor or locking device is required, as detailed on Joyce Dayton's blog. 
    Design and Configuration 
    • Configurations: Available in upright and inverted models.
    • Load Capacity: Ranges from 0.1 to 6 tons for some brands, while others, like LiftingMotion, offer up to 120 tons.
    • Options: Options include protective boots and stop pins, which can increase the closed height of the jack.
    • Design Considerations: When planning your project, remember to account for the total travel, speed, and safety, as outlined in this guide to integrating screw jacks.
    • High-Speed Designs: Specialized designs are available, such as the Neff Gewindetriebe Type R high-speed screw jack.
