Rotating energy supply – the modular system for fast rotary applications

Moving energy made easy

For several years already, igus® has been developing customised systems for circular movements with energy chains, referred to as rotating energy supplies. As a result, rotating assemblies can be supplied with energy, data and liquids, for example, on machine tools, in the field of robotics and even in bucket wheel excavators.
The igus® standard rotary modules consist of two circular guide elements. One part of the guide trough is attached to the static part of the system and the other part to the rotating part of the system. Because the rotary modules can be turned by both their inner or outer parts, the fixed end for the e-chains® can be chosen freely. In the main,
e-chains® from the E4.1 series are used for "simple" applications and energy chains of the E2.1 and E2/000 series also for rotary modules.

What does "RBR" mean?

"RBR" stands for Reverse Bend Radius and means that the e-chain® can bend in two directions. Designs with RBR can be manufactured for most igus® e-chains®. The "RBR" does not have to be identical to the standard "BR" (bend radius) of the energy chain. A wide range of circular movements can be achieved with the RBR option. Angles of rotation up to 900° have been achieved.
Tip:Find a solution for your current design and quickly, easily by submitting an inquiry about your specific application to your igus® specialist for rotating energy supplies. We will provide you with the correct sizing, simplified 3D model and an offer with prices and delivery times.

Your options for igus® guide troughs

Depending on the application in question, the e-chains® glide on surfaces made of plastic, stainless steel or galvanised steel and are guided by special channels in a predefined circular movement.
