E4.1 - ONE e-chain® series for almost all applications

The E4.1 system combines all the advantages of its three predecessors and is the best igus energy chain in the product range. The E4.1 series is stronger with the same or smaller dimensions than its predecessors. Almost all accessory components and connection dimensions are identical. With the igus E4.1 system, you can further increase the service life of your application and bring cost down at the same time.

Robust, quiet, modular. System E4.1 - utilised advantages of the proven E4 series
Opening the energy chain: Press the groove of the crossbar vertically with a screwdriver. Release with a lever movement (against the flange)
Straight running and quick assembly thanks to the inner/outer link principle. Very high stiffness, high load capacity with lateral forces due to undercut design
For particularly demanding applications
Undercut design for optimum lateral stability
Double stop-dog system and large pin/bore connection for high force absorption
High thrust force on long travels and for long unsupported lengths

System E4.1 modular system, sliding

The energy chain E4.1 is a stable, modular energy chain system that further increases the service life of your application while reducing costs. It is already in reliable use in many applications worldwide, e.g. in storage and retrieval machines, crane systems, washing systems, gantries, shuttles and many more.

The E4.1 modular system has now been expanded with the new roller chain links and glide shoes. These components
enable a technically and economically customised energy supply for every application from 12 m to 500 m travel.

E4.1: high stability and long service life
E4.1 with rollers for maximum speeds
E4.1 with glide shoes for extremely abrasive environments

E4.1 rolling with roller chain links

For maximum speeds
The integrated rollers greatly reduce the tractive/push forces on long travel distances and the energy chains used achieve a significantly longer service life. The new optimised roller chain links now also offer this advantage for the E4.1 modular system.

E4.1 gliding with glide pads

For extremely abrasive environments
In applications where extremely abrasive environmental conditions lead to excessive wear of the sliding surfaces, the new retrofittable glide shoes can increase the service life of the energy supply.
