For high-speed applications and high numbers of load cycles, cables or hoses must not be laid on top of each other without horizontal separation. The standard values for this are: travel speed over 0.5m/s and load cycles over 10,000 p.a. igus ® interior separation o ff ers a safe solution for such cases. Further guidelines for distribution The cable or hoseweight should be symmetrically distributed along thewidth of the e-chain ® . Cables and hoses with di ff erent jacket materialsmust not be allowed to stick together. If necessary, they must be laid separately. All igus ® chainflex ® cables series can be combined. The cables should always involve strain relief at the fixed and at the moving end. Exceptions aremade only for certain hydraulic hoses with length compensation issues Principle sketch bend radius R Distribution rules | Cables and hoses or other high pressure hoses (i.e. hydraulic hoses). Generally, the faster and more frequently the e-chain ® operates, the more important the exact positioning of the cables and hoses inside the e-chain ® becomes. Due to the wide variety of the possibilities, we strongly recommend you take advantage of our free consultation services for your specific applications. igus ® tip: interior separation configurator X www.igus.eu/quickchain100 An E4 extender chain with vacuum hose also guides an E2 e-chain ® here Bend radius R The bend radius of your e-chain ® depends on the thickestorsti ff estcableorhoseinyourfilling.Thebend radii shouldbeadjusted to the recommendationsof the cable or hose manufacturer. Selecting a larger radius than theminimumwill extendservice life. The specification of minimum bend radii for cables and hoses refers to normal temperatures. Other bend radii may be recommended. We recommend complete e-chain systems ® - where bend radii for all cables andhoses, interior separation and service life are optimally matched. igus ® chainflex ® cables permit the smallest bend radius of 5 x d for one million strokes. igus ® clearance space for various cables/hoses 3DCAD, configurators, service life calculation andmore X www.igus.eu Distribution rule 2: If inner height , a vertical separator or a horizontal shelf must be used to reduce the inner height. This prevents d1 and d2 from tangling. Distribution rule 1: If inner height , no separation between the two cables/ hoses is necessary. Two cables/hoses should never be left unguided on top of one another or be allowed to become tangled.
