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 450.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
* The required clearance height is HF = H + 60 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: 111mm per linkChain links per m: 9Travel: 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 = 20 [kg/m] unsupported length FLB = 4.3 m travel = 8.6 m
From 12 m to max. 400 mChain length = S/2+K2Long travel - gliding (up to max. 400 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 10m and 12m, we recommend a larger unsupported e-chain®.

Standard 01 As standard, igus® separators should be fitted every 2nd chain link!Please observe minimum clearance from the side links! e-chain®: 16 mm 80.1 Standard - for all purposes Separator, wide base for maximum holding strength and stability in e-chains® and e-tubes. 80.3 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. 80.4 For e.g. side-mounted applications Asymmetrical separator, results in defined clearance and spacers can be dispensed with. For e-chains® and e-tubes. 520.X Horizontal interior separation Locks securely into separators at both ends, giving a fixed width. Can be used as a full-width shelf for integrated interior separation or as a shelf for modular shelving at three levels.
Standard 02 As standard, igus® separators should be fitted every 2nd chain link!Please observe minimum clearance from the side links! e-chain®: 16 mm 80.2 Faster installation of cables Separator for igus® openable crossbar 450.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. 80.5 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. 520.X horizontal interior separation Locks securely into the separator at both ends, allowing a fixed width. Can be used as a full-width shelf for integrated interior separation or as a shelf for modular shelving at three levels.
Option 3: Optional As a standard feature, igus® separators should be fitted every 2nd chain linkPlease observe minimum clearance from the side links! e-chain®: 16 mm Height slot separator 509 Fast installation - can be retrofitted in existing separation system without dismantling (top and bottom notches cannot be used for shelves) Height slot separator 505For very fine interior separation. No retrofitting into an existing interior separation system without dismantling the interior separation. Quick separator T803 For fast retrofitting of interior separation or for installation without dismantling the interior separation. Locking separator 507 For environments with very high humidity (> 85%). High holding strength - thanks to asymmetric teeth. Please ensure even alignment. Recommended: one locking separator per e-chain® link. Shelves 420.X For horizontal separation. Shelves of various widths can be arranged in steps of 7mm on 11 levels (not in combination with 504, 508).
Option 4: Optional As a standard feature, igus® separators should be fitted every 2nd chain linkPlease observe minimum clearance from the side links! e-chain®: 16 mm Middle plate 503 for separation with shelves 420.X (table on the left below) in vertical increments of 7 mm on 11 levels. Locking separator 510 like a middle plate but with increased holding force in the case of applications with high humidity (> 85%). Side plate T802 like middle plate. Allows modular shelving right up to the side links. No clearance required! Clamping separator 504 Increased holding force. For applications exposed to very high humidity (> 85%). Locks with extra retention force. Recommended: one locking separator per e-chain® link. Locking separator 508 For environments with very high humidity (> 85%). Very high holding force - thanks to asymmetric teeth. Please ensure even alignment. Recommended: one locking separator per e-chain® link. Rollclip 489.27 Minimises the abrasion of hoses. Simply clamps onto the opening crossbar. The movable rollers compensate for relative movement between the e-chain® and hose. Shelves 420.X For horizontal separation. Shelves of various widths can be arranged in steps of 7mm on 11 levels.

"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.
