Advantages of igus® rol e-chain®:
- rol e-chains® are safe, space-saving and very low-maintenance.
- Cable lengths can be reduced by up to 50% (compared to festoon systems)
- Significant reduction in drive power to less than 37% for moving the rol e-chain®
- Travel distances of over 1,000 meters
- Can handle high speeds of up to 10 m/s
- Uniform rolling resistance for applications involving dirt

Rol e-chain® applications
Roller e-chain® moves the pitch at the VELTINS Arena in Gelsenkirchen
When the whistle blows in Gelsenkirchen and soccer teams compete against each other, only victory or defeat counts. But here, too, nothing works without technology. The players dominate the pitch and a maintenance-free roller e-chain® under the pitch demonstrates its strength when moving the turf.
For maximum service life with optimized design - P4HD.56R heavy-duty roller chain
The new heavy-duty roller chain fulfils all the requirements that apply to container cranes of the next generation and beyond. Longer distances, higher dynamics, short load cycles, zero failures: that, in a nutshell, is what manufacturers of ship-to-shore container cranes demand for energy supply on crane bridges. The new P4HD.56R fulfils these requirements - with maximum efficiency.
Tested for long travel distances
The roller e-chain® was tested with a travel speed of up to 8 m/s over a distance of 200m, which corresponds to 400m of travel. The fully automated system takes into account a wide range of applications in terms of acceleration and speed. In addition to the mechanical load caused by the movement of the transfer vehicle, environmental influences have an unimpeded effect on the tested e-chain® and cable.
Frequently asked questions (FAQ) for rol e-chain®
Roller e-chains should be used for applications requiring long travel distances of over 100m and high additional cable loads, in conjunction with accelerations of more than 1 m/s2 .
The service life of energy supply rollers generally depends on the roller material and the external environment. Free-running or unprotected rollers are susceptible to external influences. In igus® e-chain® systems, rollers are integrated into the chain link and "lubricated for life" with a seawater-resistant grease. Such a system does not need to be replaced over the entire service life.
Yes, while the E4/4 roller chain is known from the crane industry, among others, the need to handle high loads, long travel distances and dynamic behavior often applies to x-axis in machine tools. The 5050RHD roller chain, for example, enables travel distances of 10-800 meters with a maximum additional load of 30 kg/m. With an inner height of 80 mm, this chain can still be used dynamically. For example, amax is 50 m/s² and vmax 6 m/s.
E4/4 Roller chains come with four different inner heights, up to 7 radii, up to 42 widths, two reinforced variants and are available as e-tube from stock to ensure that it fits your machine. To be sure that the chain is used optimally, we recommend having it designed by an expert from igus®. They will check the filling carefully and also design the corresponding trough directly for you. In most cases, we can also make a reliable service life prediction based on our test data, which gives you and your system safety.
