Ball Screws

Carry: The Hercules of screw drives - a powerhouse with convincing features

Our ball screws don’t just meet expectations – they exceed them. With high efficiency, exceptional travel speed, superior durability, and Swiss precision, they give you a clear competitive advantage in demanding applications.

Reduce unnecessary costs and energy losses – Carry sets new standards in ball screw technology. Nature provides the perfect analogy: Just as an ant can carry 50 times its body weight, our Carry ball screw withstands 1,000 times its own weight – with a spindle diameter of just 40 mm.

Design features

Our rolled ball screws from the Carry series provide a cost-effective and energy-efficient solution for moving heavy loads with precision and reliability. By leveraging advanced cold-forming technology, they offer increased material strength, resulting in longer service life and reduced maintenance costs for your applications.

With optimized ball return systems, our ball screws enable faster and smoother motion, allowing you to achieve higher productivity without compromising on stability. Unlike traditional ground ball screws, our solutions help you reach higher travel speeds while avoiding critical speed limits, ensuring safe and efficient operation in demanding environments. Whether in automation, medical technology, or industrial machinery, Eichenberger ball screws help you enhance system efficiency, reduce downtime, and optimize performance with Swiss-engineered precision.

  • High load ratings: suitable for high static and dynamic loads
  • Medium to high travel speeds: through to high-helix pitches bigger than the screw diameter (p>d)
  • Extremely high efficiency (η >0.9)
  • Energy savings: Reduced drive power, energy consumption and self-heating
  • Low-friction, stick-slip-free running
  • Precision: High positioning and repetition accuracy
  • Smoothness: Highly reliable and durable with minimal maintenance necessary
  • Dirt wiper: available for challenging environments

Example applications for ballscrew drives

The high efficiency of ballscrew drives makes them especially useful for rapid motion processes involving extremely high frequency cycles of forward, backward and vertical movement. High accuracy, no backlash and travel speed are some of the most important specifications.
The force between the screw threads and the nut in the spindle is transmitted via balls circulating in a closed system. The rolling friction of ballscrews has a number of advantages compared to sliding friction or trapezoidal screws.
