E4/4 - The forerunner of the E4.1 system for long travels and applications turned by 90°
The E4/4 system is applied in two areas: For extremely long travel distances and for unsupported, side-mounted application. The famous "tongue and groove" design between two chain links enables this feature. Compression forces and stability are enhanced, whereby the power of resistance against wet and rough weathering is increased. Special roller chain links make E4/4 real specialists for long travel distances. The undercut design - the simple mounting in specified grooves - similarly enables the outstanding ESD/ATEX performance. The chain links are tightly linked to each other, because electricity can flow through them when in contact with each other (Please note: This is valid only for the special conductive material igumid ESD and is not applicable for the standard series in this catalog).
The special "tongue and groove" design grants special stability to Series E4/4, unsupported "side-mounted application."
Opening of the E-Chain®: Push down the groove of the cross bar with a screw driver. Loosen by prizing (against the clamp)
Available also as roller E-Chain® on request
You can find the right E-Chain® quickly by entering concrete parameters and with the aid of a comparison table.
Joining, separating and opening of the E-Chain® and E-Tubes.
Applications in various industrial sectors and in the igus® test laboratory.
