For applications where an extremely low-noise running of the energy chain, very high dynamics or very low abrasion is required, the motion plastics specialist igus has developed the E6.1 series of energy chains. These chains are now available in new sizes with larger inner heights of up to 62 mm.

The company igus has developed the E6.1 series of e-chains for applications where very low-abrasion energy chains are required, for example in the clean room in semiconductor manufacture. As with the predecessor series E6, instead of a pin/bore connection, elastic polymer spring elements in the side elements serve as connectors for a dampened and very smooth running of the chain. The very small pitch and contour of the chain links ensure that the polygonal effect is reduced to a minimum and the chain rolls very smoothly. Thanks to the narrower design compared to the E6, roughly 30 percent can be saved with the same inner dimensions. "Further advantages of this design principle are a very quiet and extremely low-vibration operation with only 32 dB(A)," explains Harald Nehring, authorised officer for e-chain systems at igus.
