Lubrication-free components for construction machinery vehicles

Moving cables in construction and transport commercial vehicles must be robust and well protected in order to withstand mechanical loads and environmental influences. In some cases, large cable packages need to be routed safely, e.g. in telescopic trailers and extendable low-loaders for heavy transport. Our energy chains made of corrosion-resistant high-performance plastic do this job - ideally in combination with chainflex® cables, which have been specially developed for moving applications.

Our heavy-duty plain bearings are ideal for bearing points that are subject to particularly high loads, for example in the tipping hydraulics of dump trucks. The combination of high-strength fibre composite material and embedded solid lubricants makes them extremely robust, insensitive to dirt and 100 percent maintenance-free.

Common challenges in construction machinery

Construction machinery operates in environments where components are exposed to dirt, mud, moisture and heavy loads constantly. Conventional metal bearings are renowned for suffering due to corrosion and wear, grease and oil can also accelerates wear as dust and dirt become attached. This is prominent particularly in hydraulic pivots and other high-load applications.

Issues such as this can lead to increased maintenance costs and unplanned downtime. These can all impact productivity and operating costs. Our lubrication-free components are designed to overcome these challenges by providing corrosion-resistant, lubrication and maintenance- free solutions that help improve reliability, efficiency and extend service life.

Application examples of igus components in construction and commercial vehicles

Cable routing for telescopic XXL semi-trailer

Goldhofer AG has presented a concept for an extra-long, 5-fold telescopic trailer for the transport of oversized wind turbine blades. Three energy chains from the E4 series are used for the safe and stable guidance of the heavy cable packages.

Bearings for reliable tipping mechanism for Librelato S.A

iglidur® plain bearings ensure a reliable tilting mechanism in the Librelato S.A. lorries. They replace the previously used bronze bearings, which were constantly clogged with dirt and dust and had to be regularly maintained and greased.

Slewing ring bearings for the production of thermal walls

The company EBAWE Anlagentechnik GmbH needed a special 3D head for the attachment of a high-pressure water jet nozzle, which should not be able to be inserted vertically but also at an angle to the insulation panel. This was realised with the help of our iglidur® slewing ring bearings.

Frequently asked questions

Depending on the area of the bearing within the excavators will depend on the best bearing. We have a wide range of materials, for robust, heavy duty bearings we have a range, igutex which are are ideal for high loads.

Depending on the load, speed and environmental parameters so using the online tool will help identify the best bearing

This will depend on the application but you can use the free online configurator to add the parameter details and see which plain bearing material is recommended.

Use the plain bearing configurator

Absolutely and we do regularly. We work with a lot of OEM's already replacing bearings that are worn, too heavy or too costly.
