The company Stoll relies on igus energy chains from the
Series 27i in its knitting machines. They have to fulfil high requirements: in combination with strong accelerations (10m/s² in the normal range, up to 20m/s² for quick stops) and the sometimes poor ambient conditions, such as extreme heat and oily air, the internal copper cables and hoses must not break. Our e-chains easily withstand the more than 50 million movement cycles that are not uncommon in knitting machines.
