Flexible energy supply system for rotary motion applications

Igus has launched twisterband HD, a stronger, more robust version of its twisterband rotary motion cable management system. Developed to give operational and functional reliability to rotating applications that require mixed services, for example, power, data, air or fibre optics, with high loads and small installation space.

The outer diameter of the energy chain is 300mm and height starts at 250mm, with minimal installation space requirements. High angles of rotation are said to be possible with horizontal rotary motions of around 7000° (20 full turns) and vertical to 3000° (eight full turns), while guiding energy, data and media.

Igus claims the Twisterband HD has a service life of over one million rotary cycles, even under tough conditions. Tested in temperatures ranging from -40°C to 80°C, twisterband HD is suited for use in outdoor environments, as well as indoors. The predefined minimum bend radius prevents damage to cables, while the hinge design that connects the individual segments allows fast assembly, as well as fast filling with cables and hoses.
