Ball Screws 16 - 125 mm Diameter, Ground Thread

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.

Technical-Tip: 

Steinmeyer ball screws with nominal diameters of 16 mm to 125 mm are available as ETA+ screws, which yields a clear performance advantage for your linear drive. ETA+ technology significantly reduces friction (and thus heat) while, at the same time, the rigidity increases. Life is also improved. ETA+ ball screws have near zero reversing error and may be used with much higher servo loop gain.

The nuts of ETA+ ball screws are often somewhat shorter than the double nuts shown on the following pages, but for simplicity the difference is not shown. Please inquire if a small reduction in overall nut length is desired.

ETA+ ball screws may be found on the following pages. Technical data are given in parenthesis. When inquiring, please clearly state that you want ETA+ execution.

Due to the success of ETA+, some sizes are no longer available in conventional execution.
