Unsupported - short travels

Definition - unsupported

We speak of an unsupported application, if the upper run of the energy chain does not touch the lower run along the entire travel.

Unsupported applications

The unsupported application is the most common of all application types. igus® energy chain systems are ideally suited for high dynamics and long service life. The maximum unsupported length is first of all dependent on fill weight and the selected energy chain or E-Tube.

Definition - unsupported length FLG

That is the distance between the moving end and start of radius bend of the energy chain. The unsupported length is always dependent on the chain type and the fill weight.

Example for unsupported straight FLG

The installation type FLG always yields the highest service life and can be operated with the maximum values for speed and acceleration.

Gliding - Long travels

Definition - gliding application

We speak of a gliding application, if the upper run of the energy chain is placed on its lower run.

The gliding application system of igus® energy chain

In long travels the upper run of the igus® energy chain is placed on the lower run. The upper run glides partly on the lower run and partly on a glide rail at the same height. The graphic below shows this principle. A trough is required (guide trough) for the lateral guide.

Free project planning

We suggest that you let us calculate every gliding application. The advantage of us undertaking the project planning of the igus® energy chain system is that we always work out the most cost-efficient solution for you, taking into account the technical requirements and operational safety.

Practical example for a reduced moving end

Advantages of reduced moving end:

Over 400 m travel

5 m/s speed

Fill weight up to 70 kg/m

Space-saving

Please note:

For gliding applications up to 10 meters, we recommend the use of an energy chain with larger unsupported length and unsupported installation type.

You'll receive an overview of the most varied applications in the section, Design Specifications.


We'd be glad to assist you in the selection and design of the right energy chain.
