The ESD E4.1 system combines all the advantages of its three predecessors and is the best system in the igus® range of e-chains®. Series E4.1 is stronger whilst having the same or even smaller dimensions than previous versions. Almost all accessories and mounting dimensions are identical. Increase the service life of your application with the igus® system E4.1 whilst reducing cost.
Available inner widths Bi: 50 to 200 mmAvailable bend radii R: 75 to 250 mmPitch: 67 mm/link = 15 links/m
* The required clearance height is HF = H + 40 mm (at 3 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.

The unsupported length depends on fill weightX axis: unsupported length in m FLB/FLGY axis: fill weight in kg/mLower scale: travel S in mFLB = unsupported with permissible sagFLG = unsupported with straight upper run The diagrams for unsupported lengths apply to standard e-chains® made of igumid GLW material. The values can also be used for assessing e-chain® applications in ESD special material. If the respective maximum unsupported length exceeds 80%, the suitability of the e-chain® should be verified by a practical test.
From 12 m to max. 300 mChain length = S/2+K2Long travel - gliding (up to max. 300 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 8.0m and 12m, we recommend a larger unsupported e-chain®.

"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.
