Steinmeyer Miniature Ball Screws: Medical and Lab Applications

As Germany’s leading manufacturer of miniature ball screws, Steinmeyer is proud to support many of the world’s most demanding and innovative manufacturers of medical devices and lab equipment.

Optimal Solution for the Medical Sector

The inherently smooth, precise and optimized running behaviors of our zero backlash ball screws have proven ideal for use in beam masking, biomechanics, and innovative pumps for respiratory and cardiovascular support systems.

Reliability testing, enhanced quality standards, materials traceability certs and supportive documentation for regulatory requirements can be provided.

Utilized for Lab Equipment / Pipetting / Micro-Dispensing / Medical Research

Servo-controlled linear axes are an important component of high throughput automated systems. Ball Screws enable a wider range of speeds, repeatability and accuracies.

Project examples: Multi axes stages, chemical analysis, optical focusing, cellular targeting & membrane penetration and micro-fluidic systems.

Steinmeyer Offers a Wide Range of Miniature Ball Screws:

Miniature Ground Ball Screws

  • 3 – 16 mm diameter
  • All sizes available in three nut styles: flanged, threaded, and cylindrical
  • Nut body (pilot) diameters as small as 7 mm

Miniature Rolled Ball Screws

  • 8 – 16 mm diameter
  • Same nut quality and style selection as our ground screws!
  • Choose fully assembled or stock lengths

Improved Thread Grinding Process for Ball Screws

The ultimate in smooth running.

As part of the on-going improvement of our product designs and production processes, Steinmeyer has implemented an optimized thread grinding process for our ball screw shafts.  By optimizing the process parameters and improving the supply of cooling lubricants, a much finer surface finish can be achieved during grinding.

As shown in the magnified images below, a clear improvement is achieved in the surface topography of the shaft threads.  Our testing has shown that this new thread grinding process improves the lifetime and results in much smoother running behavior.

Miniature Ball Screws for Medical Devices

When it comes to medical devices, we take our role very seriously.

Our innovative miniature ball screws ensure outstanding performance in linear motion for standard or specialized medical applications. Mechanical engineers around the globe specify Steinmeyer components because of the quality and precision that our German engineered and manufactured ball screws deliver.

  • Wide selection – includes diameter down to 3mm and pitch down to 0.5mm.
  • Made in Germany with world-class quality and craftsmanship.
  • Certified production supplier for the most demanding makers of devices and instruments.
  • Quote both rolled and ground screws come with the same high quality nuts.
  • Autoclavable designs now available!

For decades, Steinmeyer has provided precision miniature ball screws to makers of medical devices throughout the world. Our applications in the medical industry are diverse, ranging from miniature pumps to blood analysis machinery and much more. We support customers from the development stage to product manufacturing. Projects include ground-breaking clinical trials of wearable pumps that deliver compressed air to implantable balloons, and supporting a major maker of lab instruments in the launch of an automated pipetting system. These miniature screws deliver precision motion for fluid handling across a wide range of performance scenarios.

If you need a custom solution, our experienced engineers will work closely with you to meet your performance challenges. When it comes to production, you can count on Steinmeyer – whether you need several thousand units, assembly in a clean room, or other specialized configurations – we’ve got you covered. Ongoing quality controls and audits are standard procedure, and no step is too small when it comes to providing the best.

As always, Steinmeyer leads the way in innovation. We now offer special lubricants that withstand autoclaving. In addition, we recently introduced super finishing technology, available only from Steinmeyer. This step improves the surface finish of the shaft thread, resulting in lower friction torque and even smoother, quieter running than before.

When lives may depend on the medical device that goes out your door, your reputation depends on the performance of that device. You can rely on Steinmeyer to be your trusted partner for miniature ball screws.

Steinmeyer also manufactures high quality lead screws for cost-sensitive applications. Call 781-273-6220, or email for more information.
