Steinmeyer Precision Ball Screws has been dedicated to precision since 1920. In those early days, as well as today, it was close collaboration with our customers, and continued improvement of our products and services, that enabled them to rely on us with confidence. But, we invite you to experience this yourself!
Steinmeyer manufactures ball screws from 3 mm to 160 mm in diameter. For ball screws from 3 to 16 mm diameter we offer several standard shafts for various strokes, with choice of ball nut and one of two types of bearing journals. Custom versions of both nut and shaft are also available.
Precision Ball Screws 3 - 16 mm Diameter, Ground Thread Standard or Custom.
Whether you select a standard item from our extensive product range, or are looking for something specifically tailored to your needs: you just came to the right place! It's not a far-fetched guess that the smaller screw in the photo above is not a standard item. Nevertheless our list of standard screws is the right place to start collecting information.
Steinmeyer produces ball screws for machine tool and similar use with custom shafts only. For a quote, we just need a drawing or sketch that sufficiently defines the shaft.
The nut can be a standard one shown on the following pages, or custom. Even for the custom version, you may obtain useful information from the listing of technical data, since load capacities, rigidity or friction torque will be the same as in the corresponding standard version. Of course we are also prepared to assist you in selecting a nut that best meets your needs, recommend the right preload setting or provide minimum nut dimensions to yield a given life expectancy of the unit.
Steinmeyer ball nuts are ideal for rotating nut designs because they are inherently mass balanced due to the symmetrical orientation of the ball deflectors. Driven (rotating) nuts and stationary shafts offer a number of advantages over conventional layouts (and some disadvantages):
Ultra Thrust ball screws from Steinmeyer are not merely larger sizes of conventional ball screws. They have been specifically designed for the purpose of transmitting very high loads. The ball returns for example have been optimized for large ball sizes and for the specific use of such large screws. Also the robust nut body and the flange differ from conventional designs. Material selection and heat treatment take into account the special application requirements.Ball Screws for Aerospace Applications Steinmeyer produces ball screws for aerospace applications to existing customer designs, or we design and develop our own solution in accordance with customer specifications. With a proven variety of products, 40+ years of experience in ball screw production, and EN 9100 (AS 9100) approved quality system, our expertise is second to none in the global market.
- Resonance of the shaft is not as critical. Higher speeds may be reached when the shaft is not rotating.
- Pre-tensioning of the shaft is simplified, since the necessary forces do not need to be transmitted through bearings. Heating is reduced significantly.
- Stationary shafts allow easy internal cooling of the screw.
These Ultra miniature ball screws are manufactured from standard tool steel, hardened and then precision ground to meet ISO tolerances from P0 to P5. Stainless steel material is available as an option.
Steinmeyer's miniature ball screws are ideal for applications in:
- Life Sciences
- Miniature robotics
- Semiconductor processing/inspection
The Steinmeyer group is comprised of two manufacturing divisions located in Germany. August Steinmeyer GmbH & Co. KG (located in Albstadt) has been setting standards for high precision ball screws for over 40 years and prides itself on high quality,
