System E6.1: new generation of quiet running and cleanroom suitable echains®

After 10 successful years as a cleanroom and "whisper" chain, the new generation is waiting in the wings. Aside from the tried-and-tested uses of the E6, the new generation offers additional advantages which significantly simplify operation. In addition, design changes have improved accessibility to the interior, reduced weight and made assembly easier.

  • Option without camber (NC) simply by turning the inner link
  • Extremely quiet due to the small pitch and "brake" in the stop-dog system
  • (E61. at 1m/s = 32dB(A) according to igus internal test 4479)
  • Extremly low vibration
  • Low-abrasion connector system (no bolts and holes necessary)
  • Virtually no polygon effect, thereby "smooth rolling" operation
  • Smooth interior design for a long lifetime for cables and hoses
  • E61.29 series: cross bars on both sides can be snapped open and removed along the inner and outer radii
  • Weight savings approx. 30% compared to the E6 system
  • Cost-effective

Crossbar openable along inner and outer radius, either both sides

e-chain® selection aids

You can find the right e-chain® quickly by entering concrete parameters and with the aid of a comparison table.

Assembly instruction

Joining, separating and opening of the e-chain® and e-tubes.

Application examples

Applications in various industrial sectors and in the igus® test laboratory.

e-chain with 6.1 – swivelable crossbars

To protect the cables and hoses in the e-chain® even more effectively the design of the new E6.1 has been majorly advanced. Opening crossbars are very smooth and rounded, as is the transition from the chain link to the opening crossbar. All injection and marking locations were positioned outside of the cable cross-section.

Typical industrial sectors and applications

semi-conductor industry

Printer/Plotter industry

For applications with max. accelerations

When minimum noise and wear are important

Y = weight [kg/m]
The new E6.1 generation has increased acceleration capability due to weight reduction - the e-chain® is also extremely quiet and highly dynamic.
Fraunhofer test Y = Noise level dB (A)
Series E61.29 underwent noise testing in the igus® lab and demonstrates a noise level at -2 dB(A) below the already class-leading noise level of the igus® Series E6.29.

igus® for cleanrooms - suitability of E6.1 e-chains®

By using a special material, the already low abrasion of the e-chain® can be reduced even further. In many applications where cumbersome special solutions are required, a simple standard e-chain® can be used instead. A comprehensive test programme was devised and performed for both gliding and unsupported use. For many applications, the e-chains® in special materials are virtually abrasion-free. IPA tests confirm that standard igus® e-chains® meet cleanroom requirements. "Tested and certified as very good!" e-chains® for cleanroom applications demand very high wear resistance of moving parts. e-chains®, for example, must be very wear-resistant, in order to meet the normal requirements for such a sensitive environment.
