Best e-chain® for medium fill weights

Series E2.1 energy chain

More interior space, easy filling and assembly and long service life are just some of the benefits that the E2.1 series has to offer. This new generation of the two-piece energy chains was developed as an improvement on the preceding E2/000 series, which has proved its worth over a period of 15 years. The E2.1 series offers extremely fast filling from the side or from the top - along the inner or outer radius, using a chain opener or screwdriver. With all these properties, the E2.1 is ideal for use in general engineering, woodworking and metalworking industry and in machine tool construction.

Quieter

Built-in, optimised "brake" reduces noise by up to 10 dB(A)

More stable

Greater stability for more unsupported length

Faster to fill

Easy to open from the top and the side, e-chain® opener included

Crossbar openable from the left and right side or from above

Crossbar openable from the left and/or right side

The crossbar with integrated ratchet can be opened quickly and easily on both sides from above or from the side using a screwdriver.

Crossbars can be opened to more than 180°

Thanks to the hinged crossbar, the e-chain® is very accessible and therefore easy to fill.

High crossbar holding force

The crossbar and the interior separation have a very high holding force and are therefore captive. Thanks to their special design, they do not open unintentionally during operation.

Versatile connection elements and strain reliefs

Various elements ensure that the E2.1 is quickly connected to the machine and the cable is fixed in place

Mounting bracket
plastic-metal mounting brackets ensure a stable connection of the e-chain® to the machine. These are optionally available with a C-profile.

Strain relief
Ideally, the cable/hose should be strain-relieved at both ends of the e-chain®. They must be strain-relieved at least at the moving end of the e-chain®. Strain reliefs e.g. clamps, chain combs, nugget, etc.

Unique lens brake. Even quieter than the previous series

Special brake on the stop-dog ensures a noise level reduced by up to 10 dB(A).

Measured sound level in insulated sound chamber at 2 m/s

Higher additional load and unsupported length

Longer unsupported length

Force measurement in the tensile direction until the chain links break or spring apart

Opening and closing in seconds

Opening of 1 m e-chain® in 2 seconds with the igus® e-chain® opener.

Time required to completely open and reclose 1 m of chain

Chamfered pins

An insertion bevel on the pins ensures easy assembly of the chain links

Strong pin/bore connection

Stable bolt/bore connections ensure a high tensile and/or shear force absorption capacity as well as high torsional strength.

Double stop-dog

Due to the rectangular geometry, the force distribution is much better than with a round stop-dog (surface pressure formula, p=F/A). The double stop-dog ensures high stability even with long unsupported lengths.
