The ESD E4.1 system combines all the benefits
of its three predecessors and is the best system in the igus® e-chains® range. The E4.1 series are more stable with the same or smaller dimensions than their predecessors. Almost all accessory components and mounting dimensions are identical. With the igus® E4.1 system, the service life of your application can be increased still more and thereby lower costs.
Internal widths Bi: 30 up to 70 mmBending radii R: 48 up to 100 mmPitch: 30,5 mm per link = 33 links/m(1007mm)
* 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 The diagrams for unsupported length apply to the standard e-chains® in igumid GLW material. The values can also be used for the assessment of applications of e-chains® in special material ESD. In case the respective maximum unsupported length exceeds by 80%, the suitability of the e-chain® must be ensured by a practical test.
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®.

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.
