e-chains® - Series E2.1

e-chains of the E2.1 series are characterised by a long service life, particularly quiet operation and easy filling and assembly.The e-chains meet themselves to the requirements of the machine, not the other way round: You can choose the best energy chain or energy tube for safe and reliable cable guidance from over 850 different variants - also as a system consisting of chain, cables and connectors.

Shop E2.1

Quieter

Built-in, optimised "brake" reduces noise by up to 10 dB(A)

More stable

Greater stability for more unsupported length

Faster to fill

Easy to open from the top and the side, e-chain® opener included

Tech up

20% to 30% larger sliding surfaces for longer service life in gliding operation compared to previous E2/000 series
7dB(A) quieter due to integrated brake starting at size E2.26
Now also available as a fully enclosed version, a standard solution for hydraulic hoses
10% more strength compared to previous series E2/000
Good accessibility - crossbars can be snapped open on both sides, from above and from the side on the inner or outer radius

Cost down

Approx. 30% more cost-effective when the new closed design E2C.21 is used compared to previous series E2/000
Longer service life due to sliding surfaces for gliding application
Simplified interior separation system installation thanks to an integrated grid
Cable-friendly due to smooth interior
Smallest bend radius from 28mm for less required installation space
Predictive maintenance - optional with the isense add-on module

Proof

Tested in the igus laboratory: Opening of 1m e-chain in two seconds using the optional e-chain opening tool

Sustainability

Same size and connection size as previous model allows for a 1:1 upgrade. No change in the machine design required
At the end of its life cycle, leave your energy or drag chain in the igus chainge Recycling Programme utilise

Crossbar openable from the left and/or right side

Crossbar openable from the left and right side or from above

The crossbar with integrated ratchet can be opened quickly and easily on both sides from above or from the side using a screwdriver.

Crossbars can be opened to more than 180°

Thanks to the hinged crossbar, the e-chain® is very accessible and therefore easy to fill.

High crossbar holding force

The crossbar and the interior separation have a very high holding force and are therefore captive. Thanks to their special design, they do not open unintentionally during operation.

Versatile connection elements and strain reliefs

Various elements ensure that the E2.1 is quickly connected to the machine and the cable is fixed in place

Mounting bracket

plastic-metal mounting brackets ensure a stable connection of the e-chain® to the machine. These are optionally available with a C-profile.

Strain relief

Ideally, the cable/hose should be strain-relieved at both ends of the e-chain®. They must be strain-relieved at least at the moving end of the e-chain®. Strain reliefs e.g. clamps, chain combs, nugget, etc.

Unique lens brake. Even quieter than the previous series

Special brake on the stop-dog ensures a noise level reduced by up to 10 dB(A).

Measured sound level in insulated sound chamber at 2 m/s

Higher additional load and unsupported length

Longer unsupported length

Force measurement in the tensile direction until the chain links break or spring apart

Opening and closing in seconds

Opening of 1 m e-chain® in 2 seconds with the igus® e-chain® opener.

Time required to completely open and reclose 1 m of chain

Chamfered pins

An insertion bevel on the pins ensures easy assembly of the chain links

Strong pin/bore connection

Stable bolt/bore connections ensure a high tensile and/or shear force absorption capacity as well as high torsional strength.

Double stop-dog

Due to the rectangular geometry, the force distribution is much better than with a round stop-dog (surface pressure formula, p=F/A). The double stop-dog ensures high stability even with long unsupported lengths.

Lateral wear pads

The lateral wear pad increases the service life even in side-mounted applications.

Separators

Lean-separator enables lightning-fast multi-level line assignment and up to 50% faster harnessing

Internet of e-chains®: QR code

A QR code on the e-chain® speeds up spare parts procurement and assembly.

Integrated gliding surfaces

Integrated gliding surfaces ensure a long service life, even for long travels

e-chain E2.48 as cable guidance in innovative bike garage

Simply parking an expensive e-bike in the city? Many owners find that too tricky. The French company Seraap is building a new type of garage for them, in which many bikes can be stored next to and on top of each other on a shelf in a relatively small space. The energy and data cables of the control unit are securely housed in an e-chain® of the E2.48 series (E2.48.100.200).
