Steinmeyer Sponsors Medical Device Program

Engineers depend on Steinmeyer miniature ball screws for medical devices such as wearable pumps, orthotics, and more. Our quiet, smooth running screws provide precision linear motion critical for these life-changing instruments.

As part of our commitment to the medical device industry, Steinmeyer is sponsoring an educational program, presented by “Medical Device Group Boston” (MDG).

Please visit the Steinmeyer table to see the latest innovations in ball screw technology and view our German made, high quality miniature ball screws. Discover precise and reliable linear motion for medical devices and lab instruments!


Program Description:

Advances in Bionics and Medical Exoskeletons
January 16, 2019 – Regis College – Weston, MA

Come and see how much closer new technology is bringing patients to full limb utility!

Attractive artificial limbs with remarkable capabilities and natural motion are replacing the rigid prosthetics and hook-and-cable systems of yesteryear. The performance and capability of both exoskeletons and bionics have been markedly enhanced by technologies that sensitively and accurately interpret and respond to patient nerve signals and, in some recent research, send appropriate sensory signals back.

  • At this presentation, researchers Jesse Wheeler from Draper and Shriya Srinivasan from MIT will share some of their cutting-edge research in this area.
  • Paul Gudonis of Myomo and Christpher Nycz of WOI’s Automation and Interventional Medicine Laboratory will discuss the latest developments in rehabilitation robotics and their future visions for this field.
  • Christopher Morse from Ottobock will offer industry insight into what it takes to innovate in the advanced prosthetics space.

US Subsidiary of Steinmeyer Has Moved

Did you know that Steinmeyer, a world-renowned German company, has a US subsidiary that is responsible for sales and customer service in North America? The company, “Steinmeyer, Inc.”, has moved to a new location. The larger space has enabled enhanced service offerings.

The new warehouse has 25% more capacity, allowing the company to broaden its convenient stocking program. This service provides customers who place blanket orders with the advantage of having stock on hand in the USA, ready for immediate shipment.

In another popular program, select sizes of miniature ball screws are stocked and available to engineers working on prototype development. The program has now been increased to offer a wider range of miniature screw sizes and nut types.

The expanded shipping and receiving area also features the ability to handle ball screws of any length. In addition, the loading dock can accommodate a larger range of truck sizes, accelerating the delivery process.

We invite all customers to visit the new facility in Woburn, Massachusetts anytime they are in the area. Please contact Bruce Gretz, Executive VP of Steinmeyer, Inc. at 781-273-6220 or

Custom Linear Mechanisms: Sliding axes for the adjustment of two optics

Modern mechatronic systems consist of numerous precision components that must be assembled in complex configurations. Here, every detail counts. Steinmeyer Mechatronik, a division of August Steinmeyer GmbH, offers design and assembly of custom linear mechanisms for precision positioning systems for a variety of demanding applications. We have deep experience in medical devices, laboratory instrumentation, optical inspection & semiconductor positioning. Our engineers can implement your finished design or optimize your concept.

Example:  Precision Zoom Unit

Sliding axes for the adjustment of two optics

A customer came to us with a challenge. Two lenses must be precisely positioned both absolutely and relative to each other. Since the unit is exposed to stray radiation, lubrication must withstand these conditions for the long term. The basic solution consists of two sliding axes on a common guide system. Two moving sliding carriages have three carriages each, which allows them to move partially within each other to bring the lenses together as closely as possible. Each drive mechanism consists of a precision ball screw and a direct current motor with a rotary encoder. The motor encoder assembly is designed to be interchangeable for easy maintenance.

Designed for extremely dry environments

By choosing a PFPE-based lubricant and a special surface coating, the requirements for clean room compatibility and UV resistance were met. All accuracy-relevant parameters are verified by a measuring station after installation. This measuring station is located in the clean room and records accuracy, repeat accuracy, straightness, evenness and current consumption. Additional tests are performed to ensure minimum clearance in the bearing and smooth running of the drive system.

Steinmeyer has decades of experience in precision assembly. All of our systems, whether single or multi-axis, are manufactured carefully. Our high standards, monitored continuously through vigorous quality systems, are evident in every assembly we produce. We pay attention to every detail.

Real-time Condition Monitoring of Ball Screws

Steinmeyer is developing the world’s first system for real-time condition monitoring of ball screws. Called Guard Plus™, this technology measures the strain inside the ball nut in real-time to indicate loss of preload.

Preload monitoring has been talked about for years as a means to detect ball screw wear. Such data allows the scheduling of preventative maintenance, thereby reducing unplanned downtime of machines. Guard Plus finally achieves this important milestone in machine maintenance!

A prototype system will be on display at Steinmeyer booth 134154 at IMTS 2018. Please add us to your IMTS MyShow Planner and come by to speak to our engineers.

New Product Development: Improvement to Steinmeyer Wipers

Steinmeyer has recently introduced new wiper designs. We are already known for advanced wipers, but these changes drive the performance even higher.

The key upgrades include a single laser sintered piece that replaces the multi-piece metal housing in all combination wipers, and a new synthetic felt that takes the place of the natural felt.

Combination Wiper Update

Nuts with either track-to-track, liner, or Z deflectors with nominal diameters from 20 to 160 mm will now use single-piece laser-sintered sleeves. The wipers are fixed on both sides of the nut using special screws.

Nuts with external deflectors and nominal diameters from 32 to 100 mm will now use single piece laser-sintered sleeves. These are attached with a clamping element, which engages in the recess of the deflector.

Felt Update

The new synthetic felt, based on PUR ester, delivers a significant improvement in wiping with a simultaneous reduction of friction. This new material also has 5% better oil absorption capacity, resulting in improved lubricant supply. In addition, the previous method of attaching the wipers has been improved to better inhibit the formation of deposits.
