igus® e-chain system® with E4/4RHD rollers – for heavy-duty uses
The reasons why the igus® roller chain from the heavy-duty series is particularly suited for rough environments
High stability, low wear, and a maintenance-free roller system to reduce push/pull forces
1... Large pin/bore connection
High push/pull forces and reduced wear due to tight tolerances.
... travels greater than 2,625 ft possible
... low wear
... low elongation of the entire system
"In comparison to the standard E4/4, the pin strength is increased by up to 40%. “
2... low forces
The integrated, maintenance-free rollers significantly reduce the incurred forces.
... maintenance-free rollers reduce push/pull forces by up to 75%
... increased additional loads on long travels
... reduction of the required drive power
3... Heavy Duty
… no restrictions with respect to dirt loads
… high additional loads
… heat, moisture, and cold … no problem.
4... Rugged, rectangular stop dog
… high stability and rigidity
5... low wear
For a long service life on long travels due to wide glide surfaces and wear allowances
up to 9 mm wider glide surfaces in comparison to the standard System E4/4
6... fast
Even on long travels, igus® E4/4 RHD chains can achieve speeds of up to 6m/s.
... speeds on long travels, even in heavy-duty applications.
7... Cable-friendly interior separation
For higher service life due to rounded base
... nearly halve the cable wear
... less parts, more possibilities
8... Modular
The modularity of igus® systems facilitates convenient extending, shortening, expanding, and replacing.
… "infinite" width extension with extension links
… shorten and extend directly on location.
9... Everything in one system
Cables, hoses, fibre-optic cables .. everything in a single system
... reliable data and power transfers in an e-chain®
... dynamic hydraulics guided reliably.
… the world's only energy supply system that can reliably guide all media at the same time.
10... Reinforced side plates
Highly durable in outdoor environments due to side plate reinforcements of up to 9 mm.
... extended running performance guaranteed at low maintenance
... for long travels in outdoor environments.
"Up to 9 mm reinforced side plates when compared to the standard E4/4"
11... To be opened from both sides
Convenient and fast filling with crossbar system that snaps open on both sides (along the inner and outer radius)
... convenient replacement of cables
... good accessibility in all positions
12... Maintenance-free
Maintenance-free rollers with encapsulated stainless steel ball bearings
... maintenance-free, pre-lubricated and encapsulated stainless steel ball bearings for any environment
... various roller types for various applications.
13...Long travel
By using roller chains, travels of up to 800 m can be achieved.
... reduced push/pull forces
… rolling instead of gliding.
14... Torsion stable due to tongue and groove
For high stability at lateral accelerations and high torsion resistance due to "interlocking feature"
... high additional loads for unsupported and gliding operation.
... ideal for high torsion forces
15... Conductive
ATEX compliant due to the use of igumid ESD
... igumid ESD corresponds to the Ex II 2GF classification pursuant to ATEX-RL 94/9/EG
... conductive in unsupported as well as climbing operation
