E4/light ESD - Lower weight, larger inner space and lower price besides a compromise in thickness. The properties of the E4/light system have two effects: A reduced thickness of the lateral links (for all types) and a thinner crossbar for Series 14240. E4/light e-chains® achieve solutions with an optimal price-performance ratio for many industries. Especially for short travels, hanging and small standing designs. E4/light types are often the first choice.
Typical industries and applications
Available inner widths Bi: 75 up to 300 mmAvailable bending radii R: 150 up to 250 mmPitch: 91 mm per link = 11 links/m
* The required clearance height is HF = H + 60 mm (at 3 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.
A= Moving end, B= Fixed endPitch: 91 mm per linkLink per m: 11Travel: SChain length = S/2 + K
Dependency of the self-supporting length on the additional loadX-axis: unsupported lengths in m FLB/FLGY-axis: additional load in kg/mLower scale: travel S in mFLB = unsupported with permissible sagFLG = 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 12m up to max. 250mChain length = S/2+K2Long travels - gliding (up to max. 250m) 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 9,0 and 12 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.
