Motion Control – Steinmeyer Celebrates 100 Year Anniversary!
Motion Control – Steinmeyer 100 Year Anniversary!
Woburn, MA, USA, – Steinmeyer, the German-based maker of precision ball screws, marks its 100-year anniversary in 2020. The company was founded by August Steinmeyer in 1920 as a precision thread grinding shop and soon began producing micrometers as its first product. In 1965, Steinmeyer began manufacturing its signature product, precision ground ball screws.
Today, it employs over 400 workers at its Albstadt, Germany headquarters, the site of its founding. Steinmeyer now crafts an expansive line of ground, rolled and aerospace ball screws that are used in a wide range of linear motion applications.
The internationally recognized company has now grown to three divisions, bringing its total employment 680. Steinmeyer Mechatronik makes custom motion systems, and Feinmess Suhl makes custom metrology systems.
Said Bruce Gretz, Executive Vice President of Steinmeyer’s North American subsidiary, “We are proud to be part of a legacy that looks back on 100 years of tradition.”

Motion Control – Case Study – Ball Screws used in Wearable Pumps!
Motion Control – Case Study: Wearable Pumps!
The Next Generation of Intelligent Balloon Catheters Depend on Novel Designs of Ball Screw Driven Pumps
Woburn, MA –Motion Control Components Ball Screws – Case Study –
Situation:
In the realm of cardiovascular assist devices, recent developments have focused on fully implantable pumps. Among the first was HeartMate, quickly followed by Impella and HeartWare. Fully implantable devices are very expensive to develop and produce. Plus they are limited to patients who can tolerate the highly invasive procedure.
A key development in cardiovascular assist devices would be to combine the less-invasive approach of implantable balloons and external pumps with the high portability and reliability of fully implantable systems. This advance would allow the treatment of a much wider range of patients and conditions. A Steinmeyer customer set out to develop an innovative pump to achieve this advance in an intra-aortic system
Challenge:
One of the main technical challenges to this approach is designing a wearable pump that can carefully control the balloon’s pressurization. The pump must meet a demanding combination of performance requirements, including:
- Precise control of pressure
- Reversible pressurization
- Light weight
- Compact size
- Quiet operation
- Continuous performance for at least one year
Meeting these requirements was a significant challenge for their engineers. They built and tested early prototypes using traditional designs such as diaphragm pumps. But this approach required separate chambers for positive and negative pressure. The resulting systems were far too large and heavy. So they were forced to find a new approach.
Results:
Their main innovation was selecting a precision ground ball screw as the drive mechanism and pairing it with a custom engineered metal bellows as the pressure chamber. Ball screws deliver exceptional thrust density while enabling high linear acceleration in both the forward and reverse directions. Surrounded by the bellows, this results in an extremely compact and quiet design. Ball screws are also known for their high efficiency (>90%), smooth operation, and long life. Their efficiency enables the use of small motors and low power consumption, which in turn reduce the size and weight of the entire system.
The engineers turned to Steinmeyer to ensure the smoothest running, highest quality ball screw. And they also knew that Steinmeyer was extremely well-qualified to provide technical support through all stages of development. Their system is meeting all of its design requirements and will soon enter late stage clinical trials.

Future:
There is an emerging trend in the development of balloon catheters to serve cardiovascular applications. Intelligent balloon catheters may one day be key to innovation. These devices will use flexible sensors and electronics along the catheter for data collection and therapeutics. They will also incorporate balloons to apply mechanical force in the heart and arteries. Ball screw driven pumps will support these future systems as well.

Motion Control – Case Study: Precision Ground Ball Screw Drives Universal Pipetting Module!
Motion Control Case Study – Pipetting
COVID-19 Testing / Sampling Applications
Reaching New Levels of Speed, Lifetime, and Force Sensitivity
Woburn, MA –Motion Control Components Ball Screws – Case Study –
Situation:
In the area of automated laboratory equipment, servo-controlled pipetting modules are a key component of high-throughput systems. A major, global OEM had been using an off-the-shelf linear actuator to drive the pipette. This actuator had a limited range of capability in terms of speed, positioning accuracy, and force sensitivity. Although it met the minimum technical requirements and was cost-effective, engineers soon were asked to push performance to the next level.
Challenge:
The company decided to develop a next-generation system. Throughput was essential, as it wanted to target the largest hospitals and laboratories handling tens of thousands of samples annually. The pipetting module also needed to have enhanced flexibility to support a greater variety of operations. It should allow for a wider range of speeds and be highly accurate in both positioning and bottom-finding. Engineers were also tasked with achieving a 10-year lifetime with little or no maintenance. This high lifetime was critical because their business model included free field service. To meet these new requirements, the actuator would have to be redesigned. In particular, the bearing configuration did not support the required accuracy and sensitivity. The supplier was unwilling to modify its design. Company engineers realized that they would have to design a custom actuator.
Resolution:
They came to Steinmeyer for a precision ground ball screw. They knew that Steinmeyer had world-class quality and a very wide selection of miniature screw sizes. For this project, they were able to consider shaft diameters of 5mm or 6mm, with pitch down to 0.5mm! They selected a 6mm screw to meet the challenge. Company engineers conducted extensive performance testing on the first prototype quantities. They put the new module through an exhaustive regimen of motion, and measured positioning, force sensitivity, friction torque, motor current, and other parameters. They verified that their module design met all of the new performance requirements. The company has since achieved FDA approval for the new system and formally launched commercial sales.
Future Plans:
Noise minimization is important for laboratory equipment. The next generation pipetting module will look to ensure the quietest possible operation. The OEM will be evaluating our proprietary super-finishing process called optiSLITE. This technology removes the largest irregularities left over from thread grinding of the shaft. The resulting surface yields a noticeably smoother and quieter operation.
