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.
