Best e-chain® for medium fill weights

Series E2.1 energy chain

Some of the benefits that the E2.1 series has to offer are more installation space, easy filling and quick assembly. This new generation of the two-section 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

integrated, optimised brake reduces noise by as much as 10 dB(A)

Stronger

Greater strength for longer unsupported lengths

Quicker to fill

Easily openable from the top and the side, chain opener included

Crossbar openable from the left and/or right side or from above

The crossbar with integrated grid can be quickly and easily opened from both sides or from above using a screwdriver.

Crossbars can open by more than 180°

Because the crossbars can be pivoted open the e-chain® is easily accessible and to fill.

High holding force of the
crossbars

The crossbars and the interior separation offer a very high holding force which keeps them locked in place. In this way they will not open unintentionally during operation.

Versatile mounting brackets and strain relief elements

Various mounting bracket options ensure that the cable is fastened and E2.1 is quickly connected to the machine

Mounting brackets

KMA mounting brackets ensure strong connection of the e-chain® to the machine. These are optionally available with C-profile rail.

Strain relief elements

Ideally, the cables/hoses should be strain relieved at both ends of the e-chain®. At the very least, they must be strain relieved at the moving end of the e-chain®. Strain relief elements include clamps, tiewrap plates, nuggets, etc.

Innovative brake design. Even more quiet than the preceding series

Special brake on the stop-dogs ensures that the noise level is reduced by up to 10 dB(A).

Sound level measured in anechoic chamber at 2 m/s

Higher fill weight and unsupported length

Longer unsupported length

Measurement of pull force until chain links break or separate

Open and close in seconds

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

Time needed to fully open and close 1 m of chain

Chamfered pins

A chamfered pin ensures that the chain links are easy to assemble together

Strong pin/bore connection

Strong pin/bore connections ensure high a high level of pull/push force absorption and high torsional rigidity.

Double stop-dog

With the rectangular geometry, the distribution of force is considerably better than with a round stop-dog (formula for surface pressure, p=F/A). The double stop-dog ensures high strength even for long unsupported lengths.
