Tech up & cost down
motion plastics for the
solar thermal energy industry

For an ideal energy output from a solar thermal energy plant, direct sunlight and a consistently low degree of cloudiness are essential. Deserts, in particular, fulfil these requirements. igus offers different solutions for tracking systems that can withstand the tough outdoor conditions and hence avoid maintenance work and downtime. The application areas of dirt-resistant and lubrication-free plain and spherical bearings are, e.g. parabolic troughs or Fresnel solar panel systems, solar power towers and cleaning systems.

Advantages of igus solutions:

  • UV-resistant, lubrication-free and maintenance-free
  • Quiet operation without any torque fluctuations
  • Extremely low coefficient of friction due to tribo-optimised polymers
  • For confined installation spaces and where there is very little room for movement
  • Insensitive to dirt and dust
  • Long predictable service life
  • Low cost
  • More than 17 years of experience in the solar sector
