rol e-chain® - rolling cable carrier system

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.
