Product information for the e-chain E4.1

For particularly demanding applications
Undercut design for optimum lateral stability
Double stop-dog system and large pin/bore connection for high force absorption
High thrust force on long travels and for long unsupported lengths

Double closure

Proven and extremely secure opening principle. Two simple lever movements disengage the crossbar. Crossbars therefore hold reliably even with heavy filling and are still easily openable.

Double, rectangular end cap

More than two stop-dogs cannot or can hardly be synchronised. Due to the rectangular geometry, the force distribution is much better than with a round stop-dog (formula surface pressure, p=F/A). The complete E4.1 product range has the double, rectangular stop-dog.

Vertical stop-dogs and large pins

Cable and hose can simply be pressed into the chain with the thumb. This saves up to 80% assembly time.

Large pin/bore connection

Tightly toleranced and large pin/bore connections ensure a high push and/or pull force absorption capacity. Due to the tight tolerances and the resulting almost complete zero clearance, maximum acceleration can be achieved and wear is minimised.

Scaling of the crossbars

Scalable crossbars are standard for all E4 models. This makes pre-configuration with interior separation segments easier and reduces assembly time. The separators with locking cams can be positioned in 5mm increments in the crossbar and hold securely (approx. 25kg holding force of the separator in latching position). No spacers required for "side-mounted applications".

Openable lids

Cables and hoses can simply be pushed into the chain with your thumb. This saves up to 80% assembly time.

QuickLock crossbar

Two locking flaps on the top of the crossbar can be unlocked by hand or screwdriver. Lateral "sliders" then release the crossbar from the side part of the energy chain.

Undercut design

An "interlocking" of the chain links ensures a very high torsional strength of the energy chain and a high unsupported length even in side-mounted applications.

Inner/outer link principle

For straight running, high parallelism and high strength. Alternating inner and outer links ensure very straight running. Precise parallelism of the energy chain bands supports longevity.

Cable-friendly interior separation

Smooth, cable-friendly and rounded contours ensure a long service life for the cable and hose. In addition, better and more cable-friendly interior separation can now be achieved with fewer standardised parts.

Noise brake

Simple principle but highly effective. A wedge-shaped contour in the e-chains® stop-dog dampens the impact noise of the e-chain®.

Wear pad

For long service life even on long travels. Running performance of 10,000km and more guaranteed

Protection against dirt and swarf up to 850°C

igus energy tubes have been used successfully for almost 20 years to protect against swarf. Dust, dirt, oil, aggressive environments, moisture, cold and heat are no problem for the robust plastic energy supply. The optional HT material allows 850°C hot swarf to simply bounce off - no burn-in possible.

Smooth unrolling

The contour ensures better unrolling of the energy chain and easy and safe installation.

Without pretension

By simply turning the outer links, an energy chain with pretension can be quickly converted into a no camber version. No camber versions are only required for very special applications, e.g. for hanging application and where space is limited.

Few parts

Few parts made of one material, which guarantee the smallest possible clearance, are particularly important for high acceleration. The same material is ideal for material elongation or shrinkage caused by temperature differences.

Strain relief

Strain relief systems from igus have been specially developed for use in energy chain and dynamic applications. The combination of chainflex cable materials and the contacting plastic components of the chainfix strain relief systems are designed for high cable durability and maximum holding force.

Tight-sealing mounting bracket

Retrofittable and very tight. Assembled at the front, the tight-sealing plastic/metal connection (KMA) keeps out dirt and swarf all round.

Flexible modular system

The E4.1 system is highly flexible and can be customised to your application. The energy chain offers, e.g. extender crossbar for carrying hoses up to Ø 300mm, extension link for widths up to 3 metres or various noise-reducing options. For example, studs that reduce the rolling noise of the energy chain by up to 10db(A).
