1. Straight running due to inner/outer link design 2. Low-noise running due to built-in brake in the stop-dogs 3. The undercut design ensures very high rigidity and load capacity 4. 15% more tensile strength (compared to the best old E4 series), better unsupported length due to improved vertical stop-dogs 5. Openable crossbar available 385.X. Q 6. New interior separation system increases the service life of your cables by up to a factor of 4 7. "No camber" version possible simply by rotating the outer link; no rework required 8. Crossbars can be removed from both sides 9. Lid for e-tube can be opened and removed 10. Wide plastic crossbars – cable-friendly E 4.42 series available in the ESD product range Series E4.42 ESD
* 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.
A=moving end, B=fixed endPitch: 67mm per linkChain links per m: 15Travel: SChain length = S/2 + K
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 Reference example A: fill weight = 4.0 [kg/m] unsupported length FLB = 3.4 m travel = 6.8 m
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®.

Option 4: Optional
Standard 01 As standard, igus® separators are mounted every second chain link! 42.1 Standard - for all purposes Separator, wide base for maximum holding strength and stability in e-chains® and 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. 3200.XX horizontal interior separation (inner widths 50 - 250 mm). Full-width shelf locks securely into separators at both ends, giving a fixed width. Additional separators can be moved along the shelf in any horizontal direction. They can be fitted at three different heights
Standard 02 As standard, igus® separators are mounted every second chain link! 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. 42.5 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. 42.12 Lean separators The new design of the igus® lean separators allows extremely fast fitting of shelves in several layers, which significantly reduces harnessing time. Enables extremely fast replacement of individual cables in very full e-chains®. 42.6 Notch locking separators for increased holding force Notch locking separators offer higher opening forces for high humidity and/or large hydraulic hoses. They can be positioned precisely and then locked in position. 3200.XX horizontal interior separation (inner widths 50 - 250 mm). Full-width shelf locks securely into separators at both ends, giving a fixed width. Additional separators can be moved along the shelf in any horizontal direction. They can be fitted at three different heights
Option 3: Optional As standard, igus® separators should be fitted every 2nd chain link! Height slot separator 397 Fast installation - can be retrofitted in existing separation system without dismantling (top and bottom notches cannot be used for shelves) Height slot separator 391For very fine interior separation. No retrofitting into an existing interior separation system without dismantling the interior separation. Quick separator T423 For fast retrofitting of interior separation or for installation without dismantling the interior separation. Locking separator 3804 For environments with very high humidity (> 85%). Locks with extra retention force. Recommended: one locking separator per e-chain® link. Shelves 386.X For horizontal separation. Shelves of various widths can be arranged in steps of 7mm on 5 levels - see accompanying table (not in combination with 3804, 383).
Option 4: Optional As standard, igus® separators should be fitted every 2nd chain link! Middle plate 388 for modular shelving with shelves 386.X (see table below) with height increments of 7 mm (in 5 levels). Side plate 386 like middle plate. Allows modular shelving right up to the side links. No clearance required! Shelves 386.X For horizontal separation. Shelves of various widths can be arranged in steps of 7mm on 5 levels - see accompanying table (not in combination with 3804, 383).

"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.
