Tech up & cost down
motion plastics for the
hydro energy industry

Machine parts that are used for generating energy via hydropower are exposed to extreme environmental conditions: they have to withstand very high loads, be resistant to saltwater and UV radiation and continuously operate without failure. Downtime due to material wear and frequent maintenance measures can negatively affect the energy output. igus offers a large variety of customer-specific solutions that fulfil the requirements of these sources of renewable energy, and help improve the technology of the entire system. Whether wave power plants, hydropower turbines or screening plants - there are a lot of application areas for our plain and spherical bearings lead screws and energy guide systems in the hydro energy industry.

Benefits of igus products:

  • Suitable for underwater applications
  • Resistant to dirt, dust and UV radiation
  • Lubrication-free and maintenance-free for 24/7 use
  • Extremely low coefficient of friction due to tribo-optimised polymers
  • For confined installation spaces and where there is very little room for movement
  • Low noise and low vibration
  • Long predictable service life
  • Low cost
  • Customised solutions from prototype to high-volume production
