Here you can configure your Energy Chain System® individually. All entries will be copied to the Bill of Materials shown at the bottom of this page.

Series 26 - Energy chain®, not openable

1. Large pins for long service life
2. Modular interior separation
3. Double stop dog for long unsupported length and Lateral glide surfaces for side-mounted operation 4. Space-saving ratio of inner-to-outer dimensions
5. Intergrated strain relief possible
6. Side wear pads
7. Cable-friendly smooth interior.
Series 27i snap-open along inner radius can be combined with Series 27 snap-open along the outer radius

Inner widths Bi: 1.97 up to 7.87 (50 - 200 mm)
Bending radii R: 2.48 up to 9.84 (63 - 250 mm)
Pitch: 2.2 (56 mm) per link = 6 links/ft (18/m)

When to use Series 26

If snap-open accessibility along the inner or outer radius is required
If stable chain of moderate size is required
If loads are moderate
If Intergrated strain relief at the connection point is required
If easy installation is required

When not to use Series 26

If maximum stability is required
System E4, Series 280
If chip protection is required

Option 1: Vertical separators and spacers Vertical separators are used if a vertical subdivision of the Energy Chain® interior is required. By standard, vertical separators are assembled every other Energy Chain® link. These separators are the only option when compartmentalizing the interior of the non snapopen Energy Chain® such as the Series 26. Both are predominantly used for side-mounted applications.

Standard separator 260 for Energy Chains®
This separator is used for general subdivision of Energy Chain®.

NOTE ON SPACERS
Vertical separators are adjustable, but can be fixed in position by means of a spacer. Spacers are most often necessary for side mounted applications. The available inner height is reduced by .08” (2mm) per spacer (for example if one spacer is placed on either side of the separator, the overall inner height is reduced by .16” (4mm). To avoid this, place the spacers on the outside of the opening crossbar (not for long travels).

Aluminum "Super Trough"- the igus® standard The Aluminum "SuperTrough" is a modular guide trough system for long travels. Aluminum "SuperTrough" is available in low cost "basic ver- sions" and can be upgraded for heavy duty applications. This universal usage makes it the igus® recommended new standard trough system.

Excellent wear and noise levels with igus® Energy Chains® - a 9.0 dB(A) noise reduction was achieved through Aluminum "SuperTrough" with noise reduction profile insert, in combination with optimized igus® Rol E-Chain®
Very easy, universal assembly
Multiple fastening options with heavy duty brackets, bottom clamps and interface connectors
Side-mount glide strips for wear protection in high-speed
Corrosion proof through seawater resistant aluminum
Flexible assembly - connects to mounting surface, independent from profile length and location of trough section interfaces

Guide troughs are used for applications in which the upper run of the Energy Chain® glides on the lower run. The following components are required if the igus® steel guide trough is used.Guide trough without glide bars part no. 92-30, guide trough with glide bars part no. 92-31. Installation sets as a joint connection part no. 92-50. XX
.XX indicates the length of the C-profiles on which the guide trough is mounted.The standard length of the trough components and glide bars is 6.56 ft (2 m). The required total length of the guide trough is determined by the travel.
