Cost down & Tech up
motion plastics for the
wind power industry

Severe temperature fluctuations, strong winds, turbulence and sand storms: wind turbines have to work reliably even when exposed to harsh weather conditions. igus offers many solutions for wind turbines as well as for the associated equipment used in production, transport and installation. These can help you reduce downtime and costs. The components required include robust energy chains and highly flexible cables for torsional movements which are used, for example, in towers, azimuth systems and rotor blade adjustment. Wear-resistant bar stock and high-performance plain bearings, which do not need lubrication or maintenance, are ideally suited for use in rotor blade adjustment and brake systems.

Benefits of igus products:

  • Safe torsional and circular movements
  • Cable protection against vibration
  • Suitable for small installation spaces, tight radii
  • Maintenance-free and lubrication-free bearings
  • Fail-safe cables with a 36-month guarantee
  • High static and dynamic load capacity
  • Wear-resistant and dimensionally strong
  • Quiet operation
  • Constant coefficient of friction due to tribo-optimised polymers
  • Low cost
