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.igus. The height the trough must at least twice that the e-chain® height. Glide friction values for e-chains® made igumid and various glide bars 3D CAD, configurators, service life calculation and more www. Acceleration plays a crucial role the life calculation. These points must observed when using assembly-friendly igus® guide troughs.5m/s Travel speeds and accelerations Travel speeds 5m/s continuous operation are possible and use current applications. For example, E4 e-chains® achieve speeds 22m/s and accelerations 784m/s2 crash test units. They are optimally matched the e-chain® material and offer the lowest values for friction, noise and wear (Illustration the right, orange with the new high-speed glide bar, super aluminium trough series 973/974/975) Long travel "off the reel. Our system guarantee (depends the application) provides additional peace mind. The trough inner width the same the e-chain® outer width, plus 4mm for aluminium SuperTrough Along the side the trough, where the upper run cannot glide the lower run, glide bars must installed. Please consult igus®. 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."

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.

Differentiations must made between normal operational acceleration and sudden jolt acceleration such unexpected stops so-called "E-stops. Guide troughs can supplied corrosion- free materials. The sides must provide chamfered opening.
