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

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 behavior when subjected to tensile forces and their load capacity; their ease of installation was also assessed.

  • 4.9 ft unsupported length with 2.69 lb/ft additional weight
    • No sagging after 96 hours
      (96 mm)
    • 19 mm sag
  • Tensile test
    • The R4-38L copes with a tensile force of 7,481 N, which is more than
      the competitor's chain.
    • 2.200 N
  • Fracture test
    • The R4-38L copes with a tensile force of 1,590 N, which is more that
      the competitor's chain.
    • 994 N
  • Ease of installation
    • Snap open on both sides
      Link-wise cutting possible
      Interior separation possible
    • Not snap open
      Cutting to length costly
      Interior separation not
      possible
  • Conclusion: The igus® R4-38L e-tube is superior to the competitor's product with regard to all the aspects tested.
