From technical innovation and the standard to a forward-looking solution, this characterizes the evolution of roller cable beads from igus. For more than 45 years, the motion plastics specialist has been developing power supply systems that reliably guide cables for all media, such as Ethernet, servo and motor cables as well as hoses. In the beginning there were almost exclusively products for the mechanical engineering sector, the invention of the cable caterpillar more than 20 years ago caused a breakthrough in other industries. The technical basis is the integration of rollers into the cable caterpillar links that provide a huge reduction in the coefficient of friction in long travel paths. The infographic explains how much energy can be saved and what speeds can be achieved with roller cable tracks.
