Innovation and market

Whether on land, at sea, in the air or in space, our products
and services ensure perfect transfer of energy, electrical
signals, data and media.

What can a slip ring achieve? Many things work unnoticed behind the scenes –
however, our world would be different without them.
They work inconspicuously, reliably and are essential
for numerous demanding applications and products.
Transmitting data, power, air and fluid from
stationary to continuously rotating components is a
technical challenge. Slip rings are the perfect
What can we achieve? SCHLEIFRING stands for the highest level of
precision and absolute reliability when transmitting
data, power, air and fluid between moving and
stationary components. Our solutions set new
benchmarks and open up entirely new horizons for
our customers.
We've got the hang of things Particularly demanding are hybrid concepts. In radar
applications, for example, they transmit power,
coolant and data over several channels in a single

More than 230 patents A good product is only as good as the idea behind it,
and that is why we live for innovation every single
day. Thus, in the last ten years more we have
made hundreds of inventions and received more
than 230 patents.
650 specialists, including
100 engineers
The ability, the passion and the experience of our
employees form the perfect basis for outstanding
results. We not only support our customers as an
external supplier but also consider ourselves to be a
strong partner in your team.
10 per cent We conduct research systematically and
methodically with dedication, and have thus further
perfected our application-orientated research over
the past decades. About 10% of our turnover is
invested exclusively in research and development in
order to constantly redefine the limits of technical

Engineering ingenuity
made in Germany
Especially when the requirements seem to be
particularly complicated, our exceptional passion for
our work comes into effect – engineering ingenuity
in the literal sense. We do not consider ourselves to
be only technology experts, we also put our hearts
and souls into our work. Hence, truly outstanding
solutions result from good work.
Unique and first rate In step with a rapidly changing market, our core
competencies such as design, development and
manufacturing are also permanently growing. That is
why we not only have more than one thousand slip
ring designs in our portfolio, but are also
continuously adding new, custom solutions.
6,000 exclusive solutions We have thus been able to develop more than 6,000
exclusive solutions that provide our customers with
significant competitive advantages and at the same
time ensure immediate operational reliability and

Transmission technology

Contacting slip rings For contacting transmission of electrical power,
signals and data, special brushes are brought into
contact with appropriate contact surface materials. The materials
and geometry are selected according
to the individual requirements of your equipment.
Contactless slip rings We are the pioneer in contactless high-end
transmission. This enables us to transfer image data
at more than 50 GBit/sec with the very best
transmission quality. With such outstanding
achievements, we have made a name for ourselves
in the industry and have thus established ourselves
as the trendsetter. For more than four decades.
Fiber Optic Rotary Joint
We offer a varied range of fiber optic rotary joints
(FORJs) for quick and seamless transmission of the
highest data rates. For passive transmission we
produce equipment ranging from single-channel
solutions to 60-channel compact on-axis devices for
both single-mode and multimode systems. The fields
of application range from aerospace to offshore and
Up to 200kW We are also one step ahead in the field of inductive
transmission. In the industrial sector there are
presently systems in use with power ratings from
1W to 10kW, in the medical-technology industry
even up to 200kW.
