539 E4.1L The best combination of stability and low weight Moving energy made even easier - fast harnessing and time-less design Advantages of the E4.1L system: ● 30% lighter and more cost-e ff ective than the comparable E4.1 ● Very cost-e ffi cient: strong and light due to optimised e-chain ® link design ● Ideal ratio of internal and external dimensions with thinner outer links and optimised crossbar geometry ● e-chains ® and e-tubes openable along the inner and outer radius, from both sides ● Inside completely accessible for easy filling ● Very tightly fitting lids on the e-tubes, virtually no gaps or openings ● Also suitable for side-mounted, standing and hanging applications ● Lower weight, high strength and good dynamics When to use another e-chain ® series: ● For easy, tool-free opening and closing - the next generation of easy-to-assemble e-chains ® E4Q, page 580 ● When the e-chain ® needs to be extremely quiet (32dB(A)) with very low vibration E6.1, page 832 ● When the e-chain ® should have a cleanroom ISO Class 1 classification E6.1, page 832 ● If even higher strength is required E4.1, page 616 1) Approx. 50% time saving with lean interior separation compared to standard interior separation, tested in the igus ® laboratory 2) Approx. 80% time saving with CFU lean strain relief compared to chainfix CFX, tested in the igus ® laboratory 3) Approx. 67% less assembly time with E4.48L compared to E4.42, tested in the igus ® laboratory –67% 3) –50% 1) –80% 2)
