Today, resource- and energy-efficient solutions are in demand. This requires new technologies that significantly improve processes. The Swiss company Eichenberger Gewinde AG has dedicated itself to the rolling - namely cold forming - of threads and the production of ball and lead screws. The latter have established themselves particularly well in many areas of linear technology. However, as the demands of users have increased, so too have the requirements placed on the threaded spindles. The ideal component must not only meet the high performance requirements, but also be as cost-effective as possible.
Mastering the specific requirements of industries with ease - with screw drives from Eichenberger
Solving practical and increasingly demanding tasks proves to be a challenge for some designs, which is why development in mechanics is never finished. Modern drive technology in particular is perceived differently these days. Where mechanical parts used to be visible, today concealed drives are desired. They should do their job - preferably completely invisibly and silently - in the smallest of spaces. Eichenberger Gewinde AG's passion for perfect movement is constantly leading the company down new paths. This results in products that bring our partners' innovations to the forefront of the market:

Dynamics in the smallest installation space
State-of-the-art window systems ventilate automatically, darken in bright light and react automatically to rain and wind. They also report if burglars are at work or if a window is left open unintentionally. The "smart" window can therefore interact with other home technologies. The tiny, tailor-made Carry 8 x 1.5 mini ball screw drive integrated into the fitting controls the closing, locking, unlocking and tilting in an impressive way. It defies moisture and condensation and impresses with its reliability, precision and speed.
Precision in limited space
Small, precise and cleanroom-compatible: the analysis, dosing and dialysis sector places high demands on the technologies used. One special application for the Carry 4×1 ball screw from Eichenberger is in the field of biopsy (removal of tissue) for subsequent laboratory analysis. The cold-rolled ball screws from Burg/CH are characterized by high dimensional accuracy and excellent running smoothness, which has led medical device developers to successfully replace the more expensive ground versions with the Carry ball screws.
Ball screw drive provides power for servo presses
Electric servo presses, also known as joining modules, are used for joining by press-fitting, joining by forming, embossing or punching. The specifications include high precision, short cycle times, immense pressing forces and often high speeds. In modern servo presses, a lot of data is collected and evaluated, e.g. on the stroke, ram position, feed speeds, braking and acceleration ramps, etc. The presses are often oversized. Presses are often oversized. By their own admission, users utilize just 10 % of the output of a preconfigured press. The YJKP servo press kit from Festo addresses precisely this issue. At the heart of this powerhouse is the cold-formed drive element Carry. The electrically driven ball screw drive from Eichenberger converts the rotary movement of the motor into a linear movement of the piston rod. The impressive efficiency of over 90 % offers optimum drive performance. Carry combines speed and precision, creating optimum conditions even in confined spaces. The proven integrated tubular ball return underlines the robustness and load capacity. The cold-rolled Carry enables press applications with up to 17kN over an entire service life of more than 10,000 km without relubrication.
Lean back and relax: New generation of airplane seat recliners
Aircraft seats should be inviting, comfortable and extremely user-friendly. However, in order to fly more economically and therefore more ecologically, the focus is not only on the design, comfort and functionality of the seat rows, but also on weight, space savings and durability. The adjustment of the backrest, seat and foot sections of the aircraft seats was previously controlled by three separate mechanisms. Thanks to the three small, high-precision and robust Carry ball screw drives, all adjustment options can now be regulated at one and the same point in the new adjustment system.

Bioservo Technologies from Sweden is a global leader in the field of soft exoskeletons, focusing on the hand and other extremities of the upper body. The Bioservo team came up with the idea of developing a glove that could help prevent stress injuries, rehabilitate and support people in their daily activities at home or at work.
Small installation space often poses a challenge with high loads. Noiseless movements in the smallest of spaces are required. This has an impact on the requirements for the geometric environment, dimensions and the dynamic and static load ratings of the drive components. The Ironhand system was realized on the basis of Soft Extra Muscle technology. For this application, Eichenberger Gewinde AG has developed its Inspiration check and worked with the customer to find the ideal drive solution.
The requirement specifications for the mechanical drive elements of the robot hand were demanding. With the Ironhand®, high positioning capabilities with the smallest strokes and high dynamics in continuous operation have to be mastered. The focus is on safety and reliability. Maintenance and service life and, last but not least, costs play a key role. Thanks to five robust, cold-rolled ball screws from Eichenberger, the robot hand has enormous power and endurance. The hand system can provide a maximum gripping force of 80 N within milliseconds. The delicate, quiet and yet extremely resilient lead screws convert the rotary motion of the motors into a linear motion. Their impressive efficiency of over 94 % allows the use of a small, lightweight battery. In addition, the ideal pitch ratio of the spindle increases the efficiency of the movement. The "five Swiss heroes", with three ingenious single-gear feedback systems built into the nut, impress with their low weight and contribute to the cost-effectiveness of the overall solution.
