More information www. the installation dimensions section each respective e-chain®
description, you will find the measurement HF, which specifies the necessary clearance height,
taking the camber into account.
Pre-load
The largest possible unsupported length influenced the design, material and camber. All igus® e-chains® are
manufactured with camber. Please consult igus®. Upon request, can deliver e-chains® without camber for
restricted space applications however, these camber e-chains® not have the same load-
bearing capacity. Exceptions: circular
movements and most long travels.eu
Calculation the e-chain® length
If the fixed end the e-chain® located the centre the travel, the e-chain® length is
calculated using half the length travel and adding the value for the bend radius.igus.
Principle camber for igus® e-chains® required installation height
The necessary clearance
height depends the
camber the e-chain®.Pleaseconsult
igus®. The camber allows for longer unsupported lengths and increases
service life and operating safety. Placing the fixed end the centre the travel
is the most cost-effective solution because requires the shortest e-chain®, cables and hoses
