Carry is a no-wear ballscrew drive for applications that need to move heavy loads with low energy consumption. The extreme helix beyond-square thread pitch makes particularly high travel speeds possible. The cold-formed products stand out for their robustness, precision, strength, efficiency and smooth running. The animal world has available with square pitches and larger examples of Herculean performance, such as an ant carrying around 50 times its body weight. To match this, human beings would have to carry fifty times their body weight. Carry can do even more: with a spindle diameter of just 40 mm, this ballscrew drive can handle 1000 times its own weight. In this way, Eichenberger ballscrews also contribute to responsible use of resources and improved energy efficiency. Design features Thanks to the outstanding manufacturing quality and precision, Carry ballscrews are ideal for all applications where heavy loads have to be moved cost-effectively and highly efficiently. Cold forming increases material strength enormously and enables us to achieve exceptionally high lead angles when using sophisticated deflection systems. Pitch ratios such as these cannot be achieved by grinding. The extreme pitches enable unprecedented travel speeds with impressive efficiency - without reaching critical speed ranges. 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) Reduced drive power, energy consumption and self-heating Low-friction, stick-slip-free running High positioning and repetition accuracy
