Service life We offer service life calculations for your application based our extensive gliding Gliding Long travels Corrosion-free igus® guide troughs are available the material: ● Galvanised steel ● AISI 316Ti/AISI 316L stainless steel material 1. Please consult igus®. Our system guarantee (depends the application) provides additional peace mind. A) Guide trough without glide bars upper run glides the lower run B) The upper run glides the glide bars from the middle the travel. recommend the use polymer glide bars from igus®.4404 upon request ● Seawater resistant aluminium application experience. Acceleration plays a crucial role the life calculation. Important: When assembling the trough parts, the following points must be More information www. recommend the use of igus® polymer glide bars." Even these situations, igus® e-chains® prove to very durable.54 0. Important factors these tests are: Push/pull forces under both ambient and extreme temperatures ● Humidity and dirt Friction values the polymers, alone and against various glide surfaces ● Behaviour electrical cables under push/pull conditions Behaviour hydraulic and media hoses under push/pull conditions Service life, and noise generation. Technical environment Long travel applications using igus® e-chains® run water, dirt, the tropics, explosion risk areas (with special design features) and many other conditions. The sides must provide chamfered opening. Guide troughs with and without glide bars can obtained from stock for almost all igus® e-chains®." Up 100m travel pre- assembled and ready to install Automated storage/retrieval system with system and chainflex® cables travel lengthsupto80mandspeedofv=4. For example, E4 e-chains® achieve speeds 22m/s and accelerations 784m/s2 crash test units. Differentiations must made between normal operational acceleration and sudden jolt acceleration such unexpected stops so-called "E-stops. The height the trough must at least twice that the e-chain® height. In these cases, however, only few thousand cycles are required per year.
