Energy chains, bearings and cables for road construction and tunnelling machines

The components of equipment for road construction and tunnelling are exposed to high loads: dirt, dust and strong vibrations. Our energy chains, cables and plain bearings withstand these conditions with ease. The predictable service life of our products minimises unplanned downtimes. And as all our products are lubrication-free, they avoid time-consuming maintenance work. Protect the cables and hoses of your drilling devices with our energy chains made of high-performance plastic or with our hybrid plastic and steel energy chains.

The technical requirements for bearing points in construction machinery are challenging. In addition to the requirements arising purely from the mechanical loads and movements that the bearings must fulfil, there are also the adverse external influences. Construction machines are used in harsh, dirty environments.
In this brochure, you can find out how igus developed high-performance plastic plain bearings that can be used in applications that previously only worked with steel and bronze.
