Chainflex cables

Example 11: tested!Completely turnedChainflex ® cables for E-ChainSystem ® are designed for applicationin linear movements and their efficiency has been proveda million times.But industrial applications and their necessary motion sequencesbecome increasingly complex, so that special cables are moreand more required for torsional movements.The service life of the most differing constructions are yet harderto calculate for torsion applications, as no fixed sizes such asradii, travels or the like, are defined.Shielded cables however are very difficult in torsion applications.Braided shields are generally braided in the oppositedirection. Whether a cable maintains the torsional demandsis very strongly dependent on the application and type ofinstallation.In torsional movements the shield litz wires are therefore drawnin one winding direction, and the other turned in the otherwinding direction.The woven arrangement and the entailing constriction of eachwinding direction lead to a quick breakage of the shield fromthe resulting expansion of the shield litz wires.Unshielded cables, particularly all bundle-stranded Chainflex ®types, could be successfully used in many torsion applications.42At igus ® , the emphasis is not only on technology but also onbeautifully designed products.
