Energy chains for circular and spiral movements


Energy chains are the most modular way of safely transferring energy, data, fluids and air. Whether horizontally, vertically along all axes or in a circle. igus energy chains fulfil this requirement completely. Various systems for rotary and spiral movements can be selected, and properties such as modularity and versatility and a high degree of stability ensure dependability. 

The slip ring-free alternative:
As our energy chain systems do not have slip rings, media such as air, oil or water can easily be transferred without any interruption.
