Solar thermal energy

For an ideal energy output from a solar thermal energy plant, direct sunlight and a consistently low degree of cloudiness are essential. igus® offers various plain and spherical bearings for tracking systems that can withstand these harsh outdoor conditions and prevents downtimes. We will find the perfect bearing solution for your system that is resistant to dirt, UV radiation and temperature and is lubrication and maintenance-free.

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
  • Insensitive to dirt and dust
  • Cost effective

Applications in use in the Solar industry

Maintenance-free for 20 years

iglidur® plain bearings made of the material iglidur®  J UV ensure a permanently smooth operation in around 1,000 bearing points of the Fresnel collectors from Ecotherm. The dry running material was specially developed for use in UV radiation and is therefore durable even in sunlight and maintenance-free.

More cost-effective and durable alternative to rolling bearings


The parabolic mirrors from Mithras Holding are equipped with durable igus® polymer plain bearings. Unlike rolling bearings, they do not require any maintenance due to the solid lubricants integrated in the iglidur® material and these are cheaper to manufacture.
