1. Straight running due to inner/outer link design2. Low-noise running due to built-in brake at the radial stops3. The tongue and groove design ensures very high rigidity and load capacity in the presence of shear forces4. 15% more tensile strength (compared to the best
old E4 series), better unsupported length due to improved stop system and vertical
radial stops5. Crossbars for e-chain® can be removed on both sides6. Wide, cable-friendly plastic crossbars7. Improved glide surfaces – long service life8. Smooth outer contours, less dirt adhesion9. Many different ways of interior separation10. Strain relief possible with strain relief separator in the mounting bracket11. Pivoting mounting brackets with "all round" attachment possible12. Alternatively available with reverse bending radii, also on both sides

* The required clearance height is HF = H + 30 mm (at 1,5 kg/m additional load), this should be observed for all types of applications.Please consult igus® if space is particurlarly restricted.
** The calculated length corresponds to the chain length without mounting brackets.

The unsupported length is dependent on the additional load X-axis: Unsupported length in m FLB/FLG Y-axis Additional load in kg/m Lower scale: Travel S in m FLB = unsupported with permitted sag FLG = unsupported with straight upper run Reference example A:
Additional load = 2,0 [kg/m]
Unsupported length FLB = 1,25 m
Travel = 2,5 m
starting at 10m up to max. 120mChain length = S/2+K2Long travels - gliding (up to max. 120m) In this case, the e-chain® upper runglides on the lower run in a guide trough. We recommend the project planning of such a system to be undertaken by our technicians. For travels between 4.0 and 10 m we recommend a larger unsupported E-Chain®.

Variant 1: Standard
Variant 1: Standard
Note: Please observe a minimum clearance of 13 mm from the side links!
As a standard feature, igus® separators are fitted every 2nd chain link!
Standard separator T2102
Is used for vertical division. It can be used additionally for simple vertical/horizontal divisions due to its notches.
Locking separator T2101
Due to special notches in the opening crossbars
of the e-chain®, it can be locked/fixed in position in 2 mm increments. The separator cannot slide sideways during operation.
Strain relief separator T2103.Z
can be integrated into the mounting bracket and placed
in any position. It combines strain relief and interior separation of the E-Chain®.
Full-width shelf 110.X
Recommended if many thin cables with similar
or the same diameters are used. Push-in shelves can be arranged within the entire chain width of 5 mm (in 3 levels).

Aluminum "Super Trough"- the igus® standard
The Aluminum "SuperTrough" is a modular guide trough system for long travels (when E-Chains® glide on themselves, as per sketch). Aluminum "SuperTrough" is available in low cost "basic versions" and can be upgraded for heavy duty applications. This universal usage makes it the igus® recommended new standard trough system.
