PowerTrak E & EF are cable and hose carriers with rugged steel side chains and aluminum or steel carrier bars, ideal for harsh environments and high-speed operation. Links are high-strength, low-alloy steel. Low friction disks placed between links enable smooth function, and reduce wear, drag, and operating noise. Stainless steel material options are available for corrosive environments – please consult factory. E Trak are designed for use with equipment in harsh environments, including machine tools, robotics, gantry cranes, loaders, shuttle cars, gas/laser cutting torches, and more. Standard model sizes include 25E, 35E, 38E, 48E, 55E, 60E, 80E, 100E, and higher. For further custom applications, please consult factory.
