For new designs, we recommend the improved e-chain® series R4.32 from the igus® E4.1 system.+25% more unsupported length, higher stability and tensile strength, same dimensions and connection dimensions
Series R77 is available from stock in limited numbers. Product support and storage are limited as of 2012.
For questions, please refer to your igus® contact person. Thank you for your understanding
to the R4.32 series
* The required clearance height is HF = H + 40 mm (with 2 kg/m fill weight), this should be taken into account for all application types.Please contact us if you have particularly small space requirements.
** The calculated length corresponds to the chain length without mounting brackets.

Other installation types
Separators can be fitted anywhere in the e-chain® cross section. The standard separator part no. 281 offers secure stability under load with its wide base, even for large cables/hoses. If the distance between the separators should be greater, separator Part No. 281.14 can be used. Also available for the applications with energy tubes: Separator Part. No. 281T. It sits on one side in the base of the energy tube. The fastener for the lid is loose in order to allow for easy opening of the energy tube.
With the various elements of the interior separation, the e-chains® and energy tubes can be divided both vertically and horizontally. Side plates and shelves allow a flexible separation structure. Shelves of various widths can be arranged in steps of 7 mm on 3 levels. You can find recommendations for assignment in the "Design" chapter. For installing the open slotted 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® 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.
