e-chains® - Series E2.1

Series E2.1

 
e-chains of the E2.1 series are characterised by a long service life, very quiet operation and easy filling and assembly. The e-chains meet themselves to the requirements of the machine, not the other way round: You can choose the best energy chain or energy tube for safe and reliable cable guidance from over 850 different variants - also as a system consisting of chain, cables and connectors.

Tech up

Tech up

  • 20% to 30% larger sliding surfaces for longer service life in gliding operation compared to previous series E2/000
  • 7dB(A) quieter due to integrated brake starting at size E2.26
  • Now also available as fully enclosed version, a standard solution for hydraulic hoses
  • 10% more stability compared to previous series E2/000
  • Good accessibility - crossbars can be snapped open on both sides, from above and the side on the inner or outer radius
Cost down

Cost down

  • Approx. 30% more cost-effective when the new closed design E2C.21 is used compared to previous series E2/000
  • Longer service life due to gliding surfaces for gliding applications
  • Simplified installation of the interior separation system thanks to integrated grid
  • Cable-friendly due to smooth interior 
  • Extremely small bend radii from 28mm so that less installation space is needed
  • 36-month guarantee
  • Predictive maintenance – optional additional isense module
Proof

Proof

  • Tested in the igus laboratory: 1m e-chain opened in 2 seconds with the help of the optional e-chain opening tool
Sustainability

Sustainability

  • Same size and connection size as previous model allows for a 1:1 upgrade. No change in the machine design required
  • Have your energy chain recycled at the end of its life cycle with the igus Chainge recycling program
  • igus supports the plastics circular economy and is investing in chemical recycling
