TwisterBand:
compact, modular
and cost-effective
Rotary movements in minimum space - 20
times around its own axis
With the very compact igus ® TwisterBand
rotations can be implemented economically
and with low wear and low maintenance in a
confined space. Energy (in the process), data
and media are kept secure.
O 4 sizes available
O Rotary movements up to 7000° (installation
position, vertical: up to 3000°, horizontal:
7000° and more possible)
O Rotary speeds up to 360°/s possible
O Compact, modular and lightweight
O Ribbons can be shortened easily
O Minimum installation space, builds very close
around the rotary axis
O Can be reliably used in various installation
positions (horizontal or vertical)
O Cost-effective
O Easy filling
O Limited length compensation possible in
combination with igus® Chainflex® cables in
very limited spaces
Typical industries and applications
O Cable reels O Robots (robot arms, 1/6
axis, scara robots) O Tooling machines O
Leisure rides O Medical equipment O Radar
and telescope equipment OAerospace, test,
measurement, handling, lifting and installation
equipment O Wind turbines (e.g. blade
adjustment) OWherever rotary unions are used

TwisterBand
In the Netherlands the TwisterBand will be used at the musical “Soldaat van Oranje“ ensuring that a special platform can turn during the show
TwisterBand Features
360°... 3000°
An axis is to be centrally installed for
angles of rotation from 1500° rotating
and horizontal
Max. rotation angle: As a rule of thumb:
Each section gives 180° = 360° more
rotation
Film hinge: Easy access and quick filling
with cables and hoses
(TB20-44-18- / TB30-75-22-)
igus® TwisterBand:
Minimum installation space, builds very
