High speeds on long travels are distinct challenges for energy chain systems. To overcome these issues, Igus has developed a more wear-resistant glide bar, which has a service life that is five times longer. Integrated into the rail is the smart plastics EC.T sensor monitors the condition of the rail and alerts the maintenance team in advance of a breakdown. The new glide bars with the sensor are suitable for a number of applications, including linear robots in automotive production, on gantries in machine tool construction or on the 7th axis of industrial robots. The EC.T sensor measures the condition of the rail and gives maintenance recommendations when needed. It works wirelessly.
