System E4.1
igus® technologies and tricks
For long service life, high stability, ease of installation and modularity
Eliminate costly components with the E4.1 energy chain system.
E4.1 - the standard for almost any application area.
1.1... Vertical, rectangular stop dogs
For maximum absorption force and high stability in large, unsupported lengths
... max. unsupported additional load possible up to 403.2 lbs/ft (600 kg/m)
... max. unsupported lengths (FLB) 26.2 ft (8.0 m), +25% with optional XXL material
1.2... Vertical stop dogs, large pins
Better force distribution resulting in higher push/pull loads are possible
... push/pull forces up to 1,573 lbs (713 kg) possible
... additional loads up to 60.5 lbs/ft (90 kg/m) and more are possible
2... Double lock
Guaranteed high holding strength in a simple, but secure opening mechanism
... max. holding strength up to 6,744 lbs (3,059 kg)
... can be quickly opened with a screwdriver
3... Large pin/hole connection
High push/pull forces and less wear through precise tolerances
... travels over 2,624 ft (800 m) are possible
... accelerations of 32.8 f/s² (10 m/s²) and more are possible
4... Scaling of the crossbars
Simple pre-configuring with interior separation provides for a secure hold, even in side-mounted applications
... facilitates the mounting with interior separators
... absolutely even, no cable wear due to scaling
5... Swivelable lids
For quick insertion of cables from both sides
... good access from the top or bottom
... swivelable lid. The lid and bottom can be removed
6... Quick-release crossbars
25% time savings using the quick-release lock for opening and closing the energy chain
... holding strength up to 112 lbs (50.8 kg) tensile strength
... reduce assembly times by 25% - 80%
7... Tongue and groove
For high stability in cross accelerations and high torsional stability through "grip"
... additional loads of almost 17.6 lbs (8 kg) on 6.56 ft (2 m) unsupported lenghts
... ideal for side-mounted applications or high torsional forces
8... Inner/outer link design
For straight runs, high parallelism and high stability
... alternate inner and outer links provide for very straight runs
... exact parallelism in the energy chain hinges support the durability
9... Cable-friendly plastic crossbars
For even higher service life of cables through a rounded design
... Cables have the longest durability with plastic crossbars
... no plastic deformation with external impact force
10... Cable-friendly interior separation
Rounded base for higher service life
... nearly half the cable wear
... less parts, more possibilities
11... Sound brake
Dampens noise of the stop dog and rolling
... Noise levels from 33 dB(A) are possible, 46 dB(A) are measured with igus® E4 series
... many series are certified by TÜV Rheinland
12... Wear pad
For long service life even on long travels
... 6,213.7 miles (10,000 km) plus in running performance is guaranteed
... for long travels and high service life
13... 1,030 chainflex® cables from stock
... no cutting costs, no minimum quantities
... chainflex® works or your money back
14... Good protection against dirt and chips, even against hot chips
For cable protection
... hot chips up to 1,562° F (850° C) cannot burn through
... extremely tight and still easy to open
15... Wear allowance
Long service life, even for applications that are turned sideways
... lateral wear pads provide for a long service life
... an important criteria, particularly in applications turning 90°
16... Special contour of the links
Smooth-running due to soft unrolling
... silent unrolling of energy chains improve installation
17... Without pretension
by simply rotating the exterior link
... release with the same energy chain version without pretension
... no (thermal) finishing, available from stock
18... Few parts, made from one material
Quickly assembled, high dynamics and no differing material expansion
... accelerations up to 2,572.18 f/s² (784 m/s²)
... same materials
19... Strain relief of electrical cables
Space reducing and reliable chainfix program
... Three times higher tensile strength of igus® chainfix clamps
... also safe under the influence of oil, coolant, water
20... Tight mounting bracket
... chip protection up to the front edge of the Energy Tube
... profile rails can be retrofitted for strain relief
