When specifying a cable management system, there are a number of different ways to maximize the service life of your cables and hoses. One of the most crucial factors is choosing the right bend radius for the cable carrier. It is important for the bend radius, with the exception of applications with space restrictions, to be larger than the recommended minimum bend radius of the cables and media that make up the fill package.
In a previous TechTalk,Caring for Cables, we discussed how all cable carriers have a predetermined radius stopping point on each link. When a number of links are assembled, these stopping points restrict the carrier from fully pivoting and form a curve loop, or minimum bend radius.
All cable carriers have multiple bending radii to choose from—igus®, for example, offers 12 different bending radii from stock—and every manufacturer suggests a minimum bend radius. The bending radius chosen for the cable carrier will depend on the cable or hose with the largest diameter. Selecting a considerably larger bend radius than required for the fill package will extend the lifespan of the cables and hoses.
