Gliding | Long travels

Travel speeds and accelerations
Travel speeds up to 5m/s in continuous operation
are possible and in use on current applications. Corrosion-free igus ® guide
In special cases, up to 10m/s possible after troughs are available in the
consultation with igus ® . For example, E4 material:
e-chains ® achieve speeds of 22m/s and ● Galvanised steel
accelerations of 784m/s 2 in crash test units. ● AISI 316Ti/AISI 316L
In these cases, however, only a few thousand stainless steel material
cycles are required per year. Acceleration plays 1.4571/1.4404 upon
a crucial role in the life calculation. Diff erentiations request
must be made between normal operational ● Seawater resistant
acceleration and a sudden jolt of acceleration aluminium
such as unexpected stops or so-called "E-stops."
Even in these situations, igus ® e-chains ® prove
to be very durable.

We offer service life calculations for your lengths up to 80m and speed of v = 4.5m/s
application based on our extensive gliding
application experience. As developers of polymer plain bearings, we possess vast material
behaviour knowledge which we apply to the development of e-chains ® as well. Units with 200m
travels have been in operation for 8 years with minimum maintenance. Units up to 60m travels have
been in operation for 15 years with almost no maintenance. Please consult igus ® for references
and calculations for your project. The maintenance-free aspects of igus ® e-chain systems ® over
long periods and under harsh operating conditions is often the deciding factor in choosing igus ® .
Our system guarantee (depends on the application) provides additional peace of mind.

Technical environment
Long travel applications using igus ® e-chains ® run in water, in dirt, in the tropics, in explosion
risk areas (with special design features) and many other conditions. You will fi nd more details in Long travel "off the reel."

free materials. assembled and ready to
install
Calculation
Comprehensive tests place us in the position of knowing our products capabilities. Important
factors in these tests are: ● Push/pull forces under both ambient and extreme temperatures ●
Humidity and dirt ● Friction values of the polymers, alone and against various glide surfaces ●
Behaviour of electrical cables under push/pull conditions ● Behaviour of hydraulic and media
hoses under push/pull conditions ● Service life, and noise generation. If we cannot calculate
your application based on these factors, we can carry out a test for you in our laboratory. Please
consult igus ® .
