Unsupported | Short travels

For every igus ® e-chain ®
or e-tube, you will fi nd the
values for FL G and FL B in two
locations: on the following
pages in this chapter as an
overview and within every
individual series’ chapter.
They are essential for:
● Finding a suitable e-chain ®
for your fill weight and
travel distance
● Identifying the maximum
load for the selected
e-chain ®
Example of unsupported with sag, FL B
What to do if the unsupported length is insuffi cient?
If your application, fi ll weight and travel fall outside the unsupported length parameters of the
desired e-chain ® , you have the following options:
● Select a stronger igus ® e-chain ®
● Support the e-chain ® in the unsupported area. This option means restrictions for acceleration,
speed and noise as a consequence - three fundamental examples are detailed to below -
please consult igus ® if you are considering this possibility - we will gladly provide you with a
detailed proposal
● Use a multiband e-chain ® or nest two igus ® e-chains ® inside one another. (Please consult igus ® )
● Design the travel distance as a gliding application

Support of the FL G area. A) The overall straight, unsupported travel can be increased
here by a maximum of 50% of the FL G and in case of option B) by a maximum of 100%

C
Support of the FL B area. C) The overall travel distance can be extended to
a maximum of 100% from FL B
