Fabrication and Assembly of Precision Positioning Systems

Modern mechatronic systems consist of numerous precision components that must be assembled in complex configurations.  The professional assembly of these individual parts leads to a system that meets the highest demands on quality and performance.  Here, every detail counts.

We live precision

Our Steinmeyer Mechatronik divison has decades of experience in precision assembly.  We know that quality and precision can be “felt”.  Our highly qualified staff proves this every day.  All our products, whether simple linear rails or mulit-axis positioning systems, are manufactured carefully. We pay attention to every detail. Our high standards, monitored continuously through our vigorous quality systems, are shown in every Steinmeyer system.

As versatile as the application

In addition to producing our own line of precision stages, we offer fabrication and assembly services in a variety of applications.  These include medical devices, laboratory instrumentation, and semiconductor inspection.

Case Study: optiSLITE Miniature Ball Screws for Smoother, Quieter Performance


An established company that engineers and manufacturers multi-axis stages was seeking smooth, quiet, long-lasting performance from its linear motion technology. The company’s engineers decided to perform a comprehensive test on identical stages between a regular ball screw from a large OEM and new optiSLITE ball screws from Steinmeyer.

This company’s precision, multi-axis stages are used for a variety of applications in optics, semiconductor, and other instrumentation fields. The stage selected for evaluation was an X-Y model with travel of 200mm.  Each axis is driven by ball screw with a shaft diameter of 12mm and pitch of 4mm.


Once the testing began, the differences between the two were immediate and dramatic. The stage with the optiSLITE screws felt more fluid, exhibited less vibration, and produced significantly reduced noise. The test engineers could immediately distinguish between the two, making the choice of the optiSLITE ball screws self-evident.

About optiSLITE technology:

Steinmeyer’s proprietary optiSLITE ball screws employs a “super finishing” process on the shaft raceway, which removes the largest irregularities left over from thread grinding. This improved surface quality results in noticeably smoother, quieter operation. Friction torque is also lowered, and made more consistent, resulting in enhanced servo performance. Finally, the lifetime of the screw may be increased by as much as 30% for certain applications.

optiSLITE Miniature Ball Screws for Reduced Friction Torque

We are excited to introduce yet another innovation in our portfolio of precision screws – the optiSLITE miniature ball screw. These screws feature reduced friction torque and smoother running. The result is an even better positioning solution for applications in the semiconductor, optics, medical instrument, and metrology sectors.

optiSLITE ball screw shafts undergo a proprietary finishing process in their final step of fabrication. As you can see from these before and after SEM images, uring almost of the micron-sized defects on the raceway are removed. The result is a 40% reduction in friction torque!In turn this provides smoother running and enables greater servo accuracy.

optislite-vs-standard-screwoptiSLITE ball screws offer dynamic delivery of linear motion at high standards of precision and longevity, like all Steinmeyer products. The screws feature shaft diameters down to 5 mm and pitch down to 1 mm. They are available in all standard lengths and nut designs.

Xi-Plus Precision Ball Screws – Our Smoothest Raceways Yet

Steinmeyer has a long history of delivering ball screw innovations that enable our customers to design the world’s finest linear motion systems. With our new line of Xi-Plus precision ball screws, we are continuing that tradition for industrial applications that require quiet operation.

Like all Steinmeyer products, the Xi-Plus line is expertly manufactured in Germany. The shafts undergo a proprietary finishing process that removes micron-sized defects on the raceway, creating our quietest and smoothest screws ever. Those defects are responsible for high pitched “whistling” and rough running characteristics. No more noisy ball screws – no more annoying vibrations!


Xi-Plus ball screws offer dynamic delivery of linear motion at high standards of precision and longevity, like all Steinmeyer products. These screws are available in shaft diameters between 16-125 mm and all nut styles.

Customer Spotlight: Mold-Masters – Superior Melt Delivery and Control Systems

We are very pleased to share another Steinmeyer customer spotlight with you. This time, Product Development Manager of Mold-Masters, Martin Kestle, took the time to talk with us about how our ball screws are utilized in the innovative Mold-Masters E-Multi.

First, a little background on Mold-Masters; it is a world leading supplier of hot runner technology and systems. Acquired in 2013 by Milicron LLC, Mold-Masters was established in 1963. The company designs, manufactures, and supports a full range of hot runner products, including hot runner systems, hot halves, gating technologies, temperature controllers and auxiliary injection units.

Through steady technological innovation, Mold-Masters enables its customers to produce higher quality plastic parts faster, more reliably, and with greater cost efficiency. They do this by including only the highest quality components in their machines, such as Steinmeyer ball screws.

As mentioned earlier, the E-Multi, an all-electric auxiliary injection for 2-shot molding, uses Steinmeyer precision ball screws exclusively. Martin Kestle shared how he led the engineering effort behind the E-Multi product line himself, and that he selected Steinmeyer Ultra Thrust ball screws for the primary injection axis. He knew Steinmeyer’s engineering and precision manufacturing would deliver ball screws which exceeded the stringent performance and reliability expectations; it was an easy choice.

“The Steinmeyer ball screws used in our systems have gone above and beyond our expectations. Originally specified for a machine running at 100 mmps, the same screws are able to go up to 500 mmps with no failures.”

-Martin Kestle, Product Development Manger – Mold-Masters.
