Strong UV radiation, heat, wind, dust: solar plants have to operate under extreme environmental conditions. igus offers different and customised solutions that meet these exact requirements. Our motion plastics impress with their long service life, freedom from maintenance and low costs. Application scenarios for dirt-resistant and lubrication-free plain and spherical bearings are tracking systems, floating photovoltaic plants 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

igubal solar pillow block bearings convince in the lab test

In the company's own 3,800 square metre igus test laboratory, the service life, wear resistance and load capacity of igubal pillow block bearings for solar modules were examined under real loads of the daily motion sequence, simulated in a time-lapse.
 
The number of movements achieved under a load of 1.5 tons corresponded to a service life of 72 years.
