The second generation version of the igus E6 chain – the E6.1 – is up to 37% lighter, quieter and easier to assemble.

With this, the ‘polygon effect’ that can occur when an energy chain is rolling is reduced to a minimum, resulting in extremely low noise; and rigorous testing has confirmed improvements in abrasion resistance and lower wear, making it suited to clean room applications where up to ISO Class 1 – IPA is required. The weight saving improves dynamics and lowers the required drive force. The elastic polymer springelements connect the side parts of the chain to one another and prevents relative movements between the joints. As the classic pin/bore connection is no longer used, friction and abrasion are reduced to a minimum even after millions of rolling cycles. Furthermore, the optimised spring mechanism makes the E6.1 more modular.
