Ball Screw Jacks

Screw Jacks

Ball Screw Jacks offer high efficiency, precise control, high speed and long service life due to their low friction design. These actuators come in many standard models, and can be custom designed for applications, up to 50 ton, requiring accurate linear motion with high load capacities and consistent performance over time any applications.

Features & Benefits
  • Capacity
    From 1/2- to 50-Tons.
  • Long Travel Lengths
    With lifts up to 20 feet, Duff-Norton Ball Screw actuators offer the perfect solution to many linear positioning applications.
  • Configurations
    40 models available.
  • High Efficiency: Ball screw actuators convert a large percentage of rotational input into linear motion, resulting in less energy waste and lower heat generation. This efficiency can be as high as 95% compared to other systems with efficiencies as low as 20-25%.
  • Lower Energy Consumption
    Requires less power by reducing screw friction.
  • Suitable for High Duty Cycles
    The low friction and smooth operation of ball screws enable highly accurate and repeatable linear movements, making them suitable for applications demanding precise positioning, such as robotics and precision machinery.
  • Long Service Life
    Reduced friction minimizes wear and tear, contributing to a longer lifespan for the actuator system and reducing maintenance requirements.
  • High Load Capacity
    Ball screws can handle significant loads, making them suitable for heavy-duty applications like industrial automation and construction equipment. Handles full load in tension or compression.
  • Low Backlash
    Ball screw systems minimize backlash, which is crucial for applications requiring precise and consistent motion.
  • Smooth and Quiet Operation
    The rolling action of the ball bearings within the ball nut reduces noise and vibration, resulting in smoother operation.
  • Reduced Heat Generation
    The high efficiency of ball screws translates to less heat generation compared to other systems, which can be beneficial in temperature-sensitive environments.
  • Versatile Applications
    Ball screw actuators can be used individually, but also permit synchronization of multiple units as part of a larger mechanical system. They are used in a wide range of industries, including aerospace, robotics, machine tools, and automotive.
