For new designs, we recommend the improved e-chain® Series E4.42 from the E4.1 family. For questions, please refer to your igus® contact person. Thank you for your understanding to the E4.42 series
* The required clearance height is HF = H + 40 mm (at 2 kg/m fill weight), which should be observed in all types of applications. Please contact us if you have particularly confined space requirements.
** The calculated length corresponds to the chain length without mounting brackets.

From 10 m to max. 280 mChain length = S/2+K2Long travel - gliding (up to max. 280 m) Here the e-chain® is used with the upper run gliding on the lower run. We recommend letting our engineers support you when planning this type of system. In case of travel lengths between 4.0m and 10m, we recommend a larger unsupported e-chain®.

Other installation types
Option 1: Separators and spacers igus® separators should be fitted every 2nd chain link as standard! 42.1 Standard - for all purposes Separator, wide base for maximum holding strength and stability in e-chains® and e-tubes. 42.2 Faster installation of cables Separator for igus® openable crossbar 385.X. Q. One side with wide base for secure seating, opposite side is narrow for easy cable installation (light clamping). Can also be used in e-tubes. 42.3 For many thin cables Separator with narrow base for many thin cables fitted side by side. Space-saving, secure footing – for e-chains® and e-tubes. Also available for QuickLock crossbars. 42.4 For e.g. side-mounted applications Asymmetrical separator, results in defined clearance and spacers can be dispensed with. For e-chains® and e-tubes. 42.5 Locks in securely in 5mm increments Notch separator for notch crossbar with scaling. Can be positioned precisely. For e-chains® and e-tubes. Recommended for side-mounted applications. The separator 381 for e-chains® offers secure stability under load with its wide base, even for thick cables and hoses The separator 3881 with a narrow base (7 mm) for e-chains® for applications with many small cables that should respectively be separated from each other by a separator. Separators (e.g. "side-mounted" application) can be fixed in position by spacers 381.XX for e-chains®. The available inner height is reduced by 2mm for each spacer. To avoid this, the parts can also be installed on the outside of the opening crossbar (not for long travels) XX = spacer width (10, 15 and 20) Locking separator 3804 for e-chains® - with increased retention force for applications with very high humidity or extreme loads. The increased holding strength is produced by the asymmetric teeth locking into the crossbar. Please align evenly Recommended: one locking separator per e-chain® link. Asymmetrical separator 381A for e-chains® (not for tubes) with 14 mm base, for combining spacers and and separators with different widths, e.g. for side-mounted applications
Option 2: Shelves When many cables with different diameters are used - e-chains® and e-tubes can be divided vertically and horizontally 42.1 Standard - for all purposes Separator, wide base for maximum holding strength and stability in e-chains® and e-tubes. 42.2 Faster installation of cables Separator for igus® openable crossbar 385.X. Q. One side with wide base for secure seating, opposite side is narrow for easy cable installation (light clamping). Can also be used in e-tubes. 42.3 For many thin cables Separator with narrow base for many thin cables fitted side by side. Space-saving, secure footing – for e-chains® and e-tubes. Also available for QuickLock crossbars. 42.4 For e.g. side-mounted applications Asymmetrical separator, results in defined clearance and spacers can be dispensed with. For e-chains® and e-tubes. 42.5 Locks in securely in 5mm increments Notch separator for notch crossbar with scaling. Can be positioned precisely. For e-chains® and e-tubes. Recommended for side-mounted applications. Side plates 386, middle plate 388 and shelves 386.X allow flexible partitioning Shelves of various widths can be arranged in steps of 7mm on 5 levels For a more divided solutionheight slot separators 391 can be used. However, these cannot be integrated into existing shelving without removing the interior separation system The open height slot separator 397 which is open on one side, can be retrofitted without removing the existing interior separation system. For installing the open height slot separators, the top and bottom slots cannot be used for shelves

"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® glide on each other). The basic "Super-aluminium" trough is available in simple, cost-effective "basic designs" and can be expanded for sophisticated plant construction. This universal usability makes it the recommended igus® standard for guide troughs.
