RBR e-chain® Cable Chains: Optimized for High-Speed Rotary Applications

For years, igus® has been innovating customized systems for circular movements using energy chains, known as 'rotating systems'. These systems enable energy supply to rotating assemblies in applications such as machine tools and bucket wheel excavators. To expedite solutions for these applications, the motion plastics specialist has developed a standard range of rotary modules and offers a complete, installation-friendly kit system for fast rotating applications.

The standard for circular motion

  • Rotation angles up to 540° (on one level)
  • Rotation angles of 900° are possible with the igus® multi-rotation modules
  • Maximum rotation angle in minimal installation space
  • Rotation speed of up to 360°/s
  • Lighter and more compact than static guide troughs
  • Minimum displacement forces and maximum service life
  • Modular construction with standardised mounting options
  • Integrated strain relief and cable guidance directly in the guide trough
  • Determine rotating energy supply quickly and reliably with the CAD configurator

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.

Energy Chain Successfully Used in Rotary Applications

What does RBR or "reverse bend radius" mean?

"RBR" also know as "Reverse Bend Radius" means that the e-chain® can bend in two directions. Versions with "Reverse Bend Radius" can be produced for many igus® e-chain®. The "Reverse Bend Radius" does not have to be identical to the normal "BR" (bend radius) of an energy chain. In this way, a wide variety of circular movements can be solved. Rotation angles of up to 900° have been realised to date.
**Tip: Solve your current design quickly, simply and easily by simply enquiring about your specific application with your igus® specialist for rotating energy supply. We will provide you with the correct design, the simplified 3D model and a concrete offer with prices and delivery times.

What does "MRM" mean?

"MRM" stands for multi-rotation module and is effectively a multi-level RBR system. With a simple igus® rotation module (such as a standard RBR energy chain), a rotation angle of up to 540° can be achieved, depending on the energy chain size. Each additional module extends the angle of rotation by up to 360°. A simple stop-dog system carries the system's upper layer according to a defined angle of rotation. This technology means that only one control system is required for both layers.
