Series E4.28 ESD

Here you can configure your e-chain system® individually. All entries and changes are taking over to the part list which is situated at the end of the page.

Series E4.28 ESD chain, openable along both sides

The ESD E4.1 system combines all the advantages of its three predecessors and is the best system in the igus® range of e-chains®. Series E4.1 is stronger whilst having the same or even smaller dimensions than the previous versions. Almost all accessories and mounting dimensions are identical. With the the igus® E4.1 system, the service life of your application can be increased even more with lower costs.

Undercut design for best lateral stability, high shear force on long travels and for large unsupported lengths
Well suited for side-mounted applications
Noise-reducing brake and sound damper option
Inner and outer links for quick assembly, with or without camber

Available inner widths Bi: 40 to 125 mm
Available bend radii R: 55 to 125 mm
Pitch: 46 mm/link = 22 links/m

When to use Series E4.28 ESD

If a quiet type is required
For very high speed and/or acceleration
for long travel applications
For high fill weights

When not to use Series E4.28 ESD

When an extremely low vibration e-chain® is required.
E6.29 series , R6.29 series
If a one-side snap-open e-chain® is required for cost reasons
2400/2450/2480/2500 series

* The required clearance height is HF = H + 40 mm (with 1 kg/m fill weight), this should be taken into account for all application types. Please contact us if you have particularly narrow space conditions.
** The calculated length corresponds to the chain length without mounting brackets.

A=Moving end, B=Fixed end
Pitch: 46 mm per link
Chain links per m: 22
Travel: S
Chain length = S/2 + K

Unsupported length

Unsupported length versus fill weight
X axis: Unsupported length in m FLB/FLG
Y axis: Fill weight in kg/m
Lower scale: Travel S in m
FLB = Unsupported with permissible sag
FLG = Unsupported with straight upper run

The diagrams for unsupported lengths apply to standard e-chains® in igumid GLW material. The values can also be used for assessing e-chain® applications in ESD special material. If the respective maximum unsupported length exceeds 80%, the suitability of the e-chain® should be verified by a practice-oriented test.

"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® are gliding on top of themselves). The basic "Super" aluminium trough has a simple and cost-efficient designs and can be expanded for sophisticated plant engineering. Its universal design makes it the recommended igus® standard for guide troughs.

Various mounting options with bracket, clamping shoe, interface connectors
Side-mounted glide strips for wear protection on high-speed applications
Corrosion resistant due to seawater-resistant aluminium
Flexible assembly - Fastening on substructure independent of profile lengths and butt joints

Guide troughs are used for applications, for which the upper run of the e-chain® glides on the lower run. The following components are required when using the steel igus® guide trough. Guide trough without glide bar Part No. 99.30, guide trough with glide bar Part No. 99.31 Installation set Part No. 95.50. XX
.XX indicates the length of the C-profile on which the guide trough will be mounted. The standard length of the trough parts and glide rails is 2 m. The required length of guide trough is determined by the travel length.
