E4/00-NC = e-chain also available without camber
Available inner widths Bi: 40 to 300 mmAvailable bend radii R: 55 to 250 mmPitch: 46 mm / link = 22 links/m
For new designs, we recommend the improved e-chain® Series E4.28 from the E4.1 family.
For questions, please refer to your igus® contact person. Thank you for your understanding
to the E4.28 series
* The required clearance height is HF = H + 40 mm (with 1 kg/m fill weight), this should be taken into account for all application types.Please contact us if you have particularly narrow space conditions.
** The calculated length corresponds to the chain length without mounting brackets.

We recommend letting our engineers support you when planning this type of system. In case of travel lengths between 4,0 and 10 m, we recommend a larger unsupported e-chain®.

Other installation types
Option 1: Separators and spacers
Option 2: Shelves
As standard, igus® separators are mounted every 2nd chain link!
Standard separator 2201 for e-chains®
is used for vertical division. It can be used additionally for simple vertical/horizontal interior separation
by its slots
Separators can be fixed in position
by means of spacers 205.09 for side-mounted e-chains®.
The available inner height is reduced by 2 mm for each spacer. To prevent this, parts can also be installed from the outside
onto the opening crossbar (not for long travels)
Side plate 2203
Side plate 2203 and full-width shelf 220.X - this option
is recommended if many thin cables are used with
similar diameters. This solution is based on the separator 2201 (7603 for e-tube R760) through which the continuous shelves can be inserted. The 2203 side plate is used for a shelf with e-chain® series 220 when on its side,
This solution is not possible for e-tubes
Option 2: Shelves
As standard, igus® separators are installed at every 2nd chain link!
Side plates 2204, slotted separators 2202 and intermediate shelves
2200.X allow a flexible separation structure. Shelves of various widths can be arranged in steps of 5 mm on 3 levels
Side plate 6002
same as separators. Enables interior separation
up to the side links. No minimum side clearance required!
Intermediate shelf 2200.X
For horizontal separation. Shelves of various widths can be arranged in steps of different width on 3 levels

"Super-aluminium" trough - the igus® standard for guide troughs
The "Super" aluminium trough is a modular system of guide troughs for long travels (where e-chains® are gliding on top of themselves). The basic "Super" aluminium trough has a simple and cost-efficient designs and can be expanded for sophisticated plant engineering.
Its universal design makes it the recommended igus® standard for guide troughs.
1. Interface connector
2. Plastic glide bar
3. Clamping shoe
4. Glide strips
New! Rapid assistance when mounting
the e-chain® fixed end
The fixed-end module makes it easy to mount the KMA mounting bracket quickly on the super aluminium trough without drilling.
