* The required clearance height is HF = H + 25 mm (at 1.5 kg/m fill weight), which should be observed in all types of applications. Please contact us if you have particularly confined space requirements.
** The calculated length corresponds to the chain length without mounting brackets.

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

Unsupported length

The unsupported length depends on 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

Guide troughs

Steel guide troughs

1. Guide trough (blue)
2. Glide bar (black)
3. Installation set (red)
4. Individual attachment without C-profile
5. Profile rail length

Guide troughs are used for applications where the upper run of the e-chain® glides on the lower run. When using the igus® guide trough made of steel, the following components are required. Guide trough without glide bars part no. 92.30, guide trough with glide bars part no. 92.31, assembly sets as butt connectors part no. 92.50. XX
.XX indicates the length of the C-profiles on which the guide trough will be mounted. The standard length of the trough parts and glide bars is 2m. The required length of guide trough is determined by the travel length.
