For new designs, we recommend the improved e-chain® Series E4.32 from the E4.1 family.
For questions, please refer to your igus® contact person. Thank you for your understanding to the E4.32 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. 200 mChain length = S/2+K2Long travel - gliding (up to max. 200 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 6.0m and 10m, we recommend a larger unsupported e-chain®.

Other installation types
Option 1: Separators and spacers
Option 1: Separators and spacers igus® separators should be fitted every 2nd chain link as standard! 32.1 Standard - for all purposes Separator, wide base for maximum holding strength and stability in e-chains® and e-tubes. 32.2 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. 32.3 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. 32.4 For e.g. side-mounted applications Asymmetrical separator, results in defined clearance and spacers can be dispensed with. For e-chains® and e-tubes. 32.5 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 281 for e-chains® offers secure stability under load with its wide base, even for thick cables and hoses. If the distance between the separators
must be greater, separator 281.14 can be used Separator 283 with a narrow base for e-chains® for applications with many small cables that should be separated from each other. 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 prevent this, parts can also be installed from the outside onto the opening crossbar (not on long travels) XX = width of spacer (choice of 10, 15 and 20mm) Locking separator 293 for e-chains® with increased holding 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 ensure a uniform alignment (not for e-tubes). Recommended: one locking separator per e-chain® link. Asymmetrical separator 281A for e-chains (not for e-tubes) with 12 mm base, for combining spacers and separators with different widths, e.g. for side-mounted applications
Option 2: Shelves As standard, igus® separators are installed at every 2nd chain link! 32.1 Standard - for all purposes Separator, wide base for maximum holding strength and stability in e-chains® and e-tubes. 32.2 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. 32.3 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. 32.4 For e.g. side-mounted applications Asymmetrical separator, results in defined clearance and spacers can be dispensed with. For e-chains® and e-tubes. 3200.X horizontal interior separation Locks securely into the separator at both ends, allowing a fixed width. Separators can be moved freely over the shelf in horizontal direction and can be fitted at one height. Side plates 286, middle plate 288 and shelves 386.X allow flexible partitioning Shelves of various widths can be arranged in steps of 7mm on 3 levels For special applications: Separator with moulded shelf 281.S.57 (57.5 mm) or 281.S.45 (45 mm)
For a very finely divided solution, height slot separators 291 are used (not for e-tubes). However, these cannot be integrated into existing shelving without removing the interior separation system The open height slot separator 297 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.
