At Steinmeyer you obtain ball screws with

connecting dimensions according to DIN

690651 or ISO 3408.

Any size can be selected among available

nut flange shapes (round, single, flattened,

flattened on both sides) and different load

capacities.

And now you have the option to receive

Steinmeyer ball screws in Xi-Plus tech-

nology with optimized spindle surfaces

for better running features.

Standard Ball Screws:

Microscopic irregularities on the raceway

surface of the spindle can cause vibrations,

irregular running characteristics, and noise in

machines.

Advantages compared to standard

ball screws:

Through the use of innovative production tech-

nologies, the roughness of the spindle surface

can be reduced and therefore performance is

optimized. Irregular running characteristics are

virtually eliminated.

Xi-Plus ball screws deliver excellent qual-

ities.

Quiet and measurably smoother.

These improvements result in smooth-

er operation and lower noise levels

when installed in the machine.

Steinmeyer Xi-Plus ball screws have distinct

advantages over standard ball screws, most no-

tably a significant improvement in smoothness,

which can be recognized based on the band-

width of the idle torque signal.

Your benefits with Xi-Plus:

• Smooth operation

• Reduced noise

• Less vibration

• Improved efficiency

Proven reduction of torque variation.

Through studies on in-house test benches, a re-

duction in torque variation of up to 40% can be

demonstrated. We have also documented sig-

nificant improvement in running characteristics.

Significant reduction in bandwidth by up to 40%

shows the comparison of the torque measure-

ment.

Other advantages:

The Xi-Plus-Technology offers a considerable

advantage in drive technology with low noise

generation in the built-in state in the machine.

By FFT analysis (Fast Fourier Transformation) of

this signal, improvements in the noise of ball

screws can be shown. The results shows, that

the frequency which leads to most noise devel-

opments is completely removed.

Feel free to contact us.

Ball Screw Assemblies for mechanical engi-

neering with the spindle shaft are only available

according to customer drawings. For a quote

we need a drawing of a sufficiently well-defined

spindle shaft. A standard nut can be supplied or

designed according to your requirements.

We will gladly give you a quote on price

and delivery information. Please provide

simply a drawing or a sketch.

Combine Xi-Plus and ETA+.

The spindle technology Xi-Plus can be combined

with the proven ETA + -nut technology.

The two techniques together provide the best

low-friction running characteristics for an im-

proved life of your ball screw and your machine.

The ETA+-technique.

Nuts of ETA+ ball screws are often shorter than

conventional double nuts, have lower friction, and

have improved durability with excellent rigidity.

Due to the great success of ETA+, some sizes

are no longer produced in conventional designs.
