e-chains® comparison test: igus® plastic e-tube R4.38L vs. competitor's enclosed energy chain in hybrid design (plastic/metal)

e-tube R4.38L

In a comparison test in the industry's largest test laboratory in Cologne, igus® compared its plastic R4.38L energy chain with a competitor's product. In a fracture test, the two chains were evaluated in respect of their appearance, their behaviour when subjected to tensile forces and their load capacity; their ease of installation was also assessed.
