Energy chains of the E4Q/R4Q series

Easy handling - Opening and closing of an energy chain completely without tools

E4Q/R4Q series energy chains have been developed to offer the best possible solution for unsupported and long travels. Based on the robust and proven E4.1 energy chain standard, the new range brings a long service life and a high degree of modularity.
Typical application areas: machine tools, cranes, automation systems

Tech up

Tech up

  • Tool-free opening and closing
  • Reduced projections in the interior, for easier filling with open e-chain® 1
  • 15% higher pull-out strength of the crossbars 1
  • 10% less weight due to material recesses 1
  • Also available 17dB(A) quieter due to noise dampening parts made of noise-reducing material 2
Compared to System E4.1
Compared to 4040C series

Cost down

Cost down

  • 40% less assembly and installation time compared to the E4.1 system
  • Up to 35% saving possible in application in the borderline area 3
  • 36-month guarantee
  • Predictive maintenance – optional with the isense additional module
Due to a higher fill weight, the more cost-effective smaller
series can be used if necessary



  • Proof of noise: 17db(A) less than 4040C 




  • 10% less material = 10% less energy consumption during production
  • Have your energy chains processed as part of the igus "chainge recycling programme"  no matter which manufacturer they came from
  • igus supports the circular economy for plastics and is investing in chemical recycling

Decisive design characteristics of the E4Q/R4Q series


System E4Q/R4Q

Tool-free opening and closing.

System E4Q/R4Q

Four stop-dogs for maximum strength in any installation orientation.

System E4Q/R4Q

Less material in places where it does not add to strength.

System E4Q/R4Q

Optional noise dampeners for even quieter operation.

System E4Q/R4Q

Interior separation product range, also for complex division.

System E4Q/R4Q

Notches in the crossbar for secure grip of the separators.

System E4Q/R4Q


Optional noise dampening – new concealed system for noise reduction. Can be retrofitted any time. Rubber elements attached to the horizontal stop-dogs additionally dampen the impact noise of the already very quiet e-chains. 17dB(A) less noise than that of Series 4040C.


Two vertical and two horizontal stop-dogs per link provide more rigidity for the E4Q and a greater unsupported length or higher fill weight are possible.  20% more stability compared to the E4.1.


Crossbars (e-chain)/lid (e-tube) – the e-chain and e-tube can be opened and closed without any tools at all. Crossbars and lids/shelves lock in the side section for even greater holding forces. The e-chain/e-tube can be filled in considerably less time. 40% faster filling than E4.1.


Reduce weight – New findings have allowed material to be left out where it has no function with regard to the load on the e-chain . This approach has been taken inside, between the stop-dogs, and outside. Nature-inspired rounded shapes were used for the design. 10% less weight than E4.1.
