Igus has developed a lighter version of the E4.1 that also offers more filling space for cables and hoses and a new mechanism for quickly opening crossbars on both sides of the chain simultaneously.

The E4.1 light extends the modular energy chain range, which already comprises more than 70,000 parts for almost every energy chain application.

According to Igus, it is a cost-effective system that enables customers to build smaller equipment.

The specially designed outer links set the pretension (or camber), allowing assembly without pretension to be carried out for cramped conditions or for vertically hanging energy chains.

For designs with a change of direction of rotation, such as in zigzag applications, the direction of bending radius can be varied through the rotatable inner link.

The E4.1 light’s tongue and groove design, which interlocks the chain links, ensures good torsion resistance and high stability, particularly for side-mounted applications.

For applications requiring high filling weights and long self-supporting distances, the double stop system with large stop-dog surfaces helps ensure optimum load distribution.

Both the brake and stop-dog systems create a noise-reducing effect that is claimed to result in a particularly smooth running chain.

The interior separations are easy to use and optimised to be cable friendly.

They are made up of only five wear-proof and abrasion-optimised plastic separator bars that can be combined and interchanged.

Igus

Igus is the largest producer of reinforced plastic energy chains and injection-moulded polymer bearings. The range of polymer bearings includes Iglidur plain, Igubal spherical and Drylin linear bearings. They offer an excellent price-to-life relationship and are developed under the toughest conditions. They are oil, maintenance and lubrication free, low wear, resistant to dirt and dust, corrosion free and simple to fit. Igus also has the data to precisely predict the lifetime of these bearings within a specific application.

Energy chains are the umbilical cord of modern machines. They minimise downtime and protect, support and extend the service life of cables and hoses. The broad range incorporates more than 30,000 innovative, low-cost products. From the smallest ‘micro’ chain to the largest chain in the world, the E4.350, Igus energy chains are capable of long and short travel distances at high speeds in all axes.

Igus also has its own cable series, Chainflex, specially designed with energy chains in mind. They are highly flexible cables, offering a long service life and very small bending radii. A wide range is available, from small signal cables to large power cables, high-speed data cables and glass fibre-optic cables.

The company’s energy chains and Chainlflex cables can be delivered as a fully harnessed and pre-assembled Readychain system, cutting purchasing, warehousing and installation costs.
