Chain length = S/2 + K

Unsupported length

Dependency of the unsupported length on the additional load
X axis: Unsupported length in ft FLB/FLG
Y axis: Additional load in lbs/ft
Lower scale: Length of travel S in ft
FLB = unsupported with permissible sag

Guide troughs

Aluminium "Super Trough" - Basic Version

Guide trough "Super-Alu", "Heavy Duty"

Guide troughs made of steel

1. Trough side parts, aluminium, 6.56 ft (2 m)

2. Glide bar, plastic, 6.56 ft (2 m)

3. Plastic glide strips*, sidewise, 6.56 ft (2 m)

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.

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 aluminium
Flexible assembly - connects with underground, 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.
