The Igus® System E3 combines small pitch, smooth running, low noise, stability, easy installation and cost-effectiveness. The resilient element as a connector replaces the pin and bore and prevents relative movements between the joints. To reduce the manufacturing and assembly costs, the spring band is not individually mounted over a length of ten ring members.
Another fulfilling development goal of E3 is a faster and easier access to cables by zipper system. A modified spring element made of electrically-conductive material that connects the links of the chain mechanically and electrically, ensuring permanent constant conductance, even at high bending stress and in any position.
