E4/4 - The forerunner of the E4.1 system for long travels and applications turned by 90°

The E4/4 system is employed in two areas: with extremely long travels and unsupported, side-mounted applications. This is made possible by the famous "undercut" design between two chain links. Compressive strength and rigidity are increased, which provides for greater resistance to wet and rough weather conditions. Special roller chain links make E4/4 into a true specialist for long travel distances. The undercut design also allows excellent ESD performance. The chain links always fit tightly together; only when there is good contact between them it is possible for electricity to flow (please note: this only applies to the special conductive material igumid ESD and does not apply to the standard series included in this catalogue).

e4 The special "tongue and groove" design grants special stability to Series E4/4, unsupported "side-mounted application."
e4 Opening of the e-chain®: Push down the groove of the cross bar with a screw driver. Loosen by prizing (against the clamp)
e4 roll Also available as roller e-chain® on request

e-chain® selection aids

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

Installation instructions

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

Application examples

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