dry-tech® bearing technology



The alternative to a cable reel - reduce cable wear and reliably guide different media

Routing many different cables in a small space. e-spool® uniquely combines two different energy supply systems: one standard e-chain® is guided by a roller and always provides the correct length and tension of the energy supply system through an integrated spring. In the starting position, the e-chain® is rolled up completely to save space. The twisterband connects the roller with the shaft end block, which serves as an interface to the supply side cables.

No tensile stress on the cables

Different media and diameters in one drum

Energy supply possible in all directions (horizontal, vertical, diagonal … everything works with one chain)

Space-saving, no "chain festoons"

No lower run or guide troughs, paths remain free

Cable diameters up to 17 mm


Typical industries and applications

Telescopic applications

Light and stage technology

Space-saving alternative to zig-zag solutions

Please contact us if you have any of the following application parameters:

  • Outdoor applications
  • e-spool® applications that are operated upside down in public areas (spectator stands, stages, etc.)
For the applications mentioned, the e-spool® system may have to be specially secured.
Please contact your sales representative for this. 

When to use the e-spool® series:

When many different cables should be routed in very confined spaces

When different media (power, air, liquids) should be routed together in one system

When not to use it:

With cables with large bend radii

With very high loads that have to be guided vertically


More flexibility:

Unlike sliding contacts, data cables compressed air and fluids can also be permanently connected and can even be replaced or modified at any time.

General filling rules for the e-spool®

due to the particular mechanical stresses in an e-spool®, we recommend using igus® chainflex® cables. We also recommend that you observe the following filling rules:

Please put cables only side by side in the linear chain. Never put several cables on top of each other!!

Where possible, cables with a TPE outer jacket should be used for unshielded cables

Shielded cables should be from the CFROBOT range.

Where possible, use separators to protect cables against cross-over and abrasion against other cables.
To save space, install the separators alternately in segments positioned one behind the other.

Insert cables sorted according to diameter and/or bend radius.
Insert thin, small ones in the inside then increasingly larger ones outward

Apply strain relief on both ends of the cable. The cable tie wrap plate must not be installed in the e-chain® direction

Always install cables in the twisterband close to the axis of rotation with space on the outside.

Always install cables in the twisterband with a slight gap from the axis of rotation

Notes for installation
For applications that move horizontally, a smooth surface is needed for the
e-chain® to travel over.
