Spectacular design features and special material solutions

About two and a half years ago, energy chain expert igus® presented their first prototype from its new energy chain "E4.1" series. Now, the complete supply range of this new generation of energy chains is available for delivery ex-stock.

The new "E4.1" family is a further development of the well-known "E4" igus® system that is in use millions of times all over the world. It combines the best design ideas of the two energy chain variants "E4/4" and "E4/100" in one single universal solution, with numerous new design features from the company, also with a wide supply range of five different interior heights from 21 to 80 mm as well as widths from 30 to 600 mm.

Principle of inner/outer side-link
Thanks to the combination of inner and outer side-links, the user has the possibility of choosing different configurations.  Firstly, does an energy chain have to be designed with a high pre-tension and correspondingly large self-supporting length?  Or instead with little pre-tension, which is more suitable in cramped conditions or when used in vertical hanging or standing applications? The patented trick here: the outer side-link is simply turned, controlling the pre-tension. If, on the other hand, the inner side-link is turned, the rotation of the link is changed, and thus the direction of rotation of the energy chain. This makes applications such as "zigzag" possible, for example.
