The new energy tube R4.1 light combines the design tricks of several successful energy chain series. As in the proven E4.1 system, the form-fit tongue and groove provides – an “interlocking” of the chain link – for torsional stiffness and high stability in unsupported and side-mounted applications. The R4.1 light product family was specially designed for machine tools, which combine the most important requirements such as stability, tightness and assembly speed with light weight in a smart way. In addition, the R4.1 light has an extremely cable-friendly interior space and a reasonable price.
