Energy supply systems and bearings for wind turbines

Strong temperature fluctuations, high wind loads, turbulence, sandstorms: wind turbines must function reliably in harsh weather conditions. igus® offers you a large selection of high-performance plastic components for wind turbines and their production facilities, transport and assembly. These include robust, compact energy chains and highly flexible cables for torsional movements, which increase the reliability of the system in towers, azimuth systems and rotor blade adjustments, for example. Wear-resistant bar stock and heavy-duty plain bearings, which do not require external lubricants or maintenance thanks to incorporated solid lubricants, are ideal for use in rotor blade adjustment and braking systems.

Tested for real use in the test laboratory

All products are tested for wear and load-bearing capacity under real conditions in the igus® test laboratory, the largest in the industry. The results are fed into our tools for calculating service life and enable precise predictions to be made about durability.

Upon request, igus® also carries out customer tests to test the use of the products under very individual conditions.
