E4.1L - high dynamics, light and cost effective

All-rounder e-chains® and e-tubes for outstanding dynamic responsiveness. The E4.1L series has been developed to combine the advantages of the E2/000 and E4.1 in one series. The strength and stability of the E4.1 system combined with the easy accessibility of the E2/000 system. The E4.1L system is the ideal energy chain for mechanical engineering and applications of all kinds where there must be an optimum relationship between technical requirements and economic efficiency.

New, particularly cable-friendly interior separation program available.
Pivoting and rigid KMA mounting brackets available.
KMA mounting brackets with circumferential fastening options.

e-chain® with crossbars at every link, swivel lid on 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.

E4.1L e-chains® with 4-part structure

Low weight and high strength

Ideal ratio of inner and outer dimensions with thinner outer links and optimised crossbar geometry

30% lighter and lower-priced than E4.1

e-chains® and e-tubes openable along the inner and outer radius, from both sides

Very tightly fitting lids, virtually no gaps or openings

Openable along inner and outer radius

Inside completely accessible for easy filling

Typical industrial sectors and applications

Cost-effective alternative for E4.1

for unsupported applications

If the strength of the E2/000 is insufficient, but an E4.1 is too big
