Comparison of unsupported length

How does the unsupported length of the igus® e-chains® Series E2-15 and 08 differ under load?
To answer this question, both e-chains® were charged with a load of 0.67 lb per foot in the igus® laboratory.
 
The result: Under the same load and at identical unsupported length, the e-chains® of the E2-15 series have about 80% less sag than e-chains® of the 08 series (E2-15 = 4 mm sag; Series 08 = 21 mm sag)
 
With the more stable e-chain® E2-15, highly dynamic applications can be implemented under more load than with the e-chain® 08.
