Durable, maintenance-free components for renewable energies

Energy generation, especially from renewable energy sources, requires reliable and durable technology solutions. The various systems are often exposed to extreme environmental conditions such as UV radiation, temperature fluctuations, high wind loads, dirt and dust and have to withstand these for years.

Adapted to the respective system, we offer you special solutions made of high-performance polymers that help you to improve your technology, optimise your system and reduce costs.

Advantages of igus® products:

• Lubrication and maintenance-free
• UV-resistant
• Insensitive to dirt and dust
• Resistant to weathering
• Corrosion-free
• Long, predictable service life
• Customised solutions

The new generation of our solar tracker-bearing

More fun with the sun! With our ESQM 2.0, we are taking our tried-and-tested pillow block bearing for tracking solar modules to the next level and making it even more robust, compact and easy to install:

• 3 times higher UV resistance thanks to optimised housing and spherical cap material
• 20 mm lower installation height thanks to metal bracket on the upper part of the housing
• Recesses for cable guidance along the profile
• Easier installation thanks to U-alignment of the spherical ball and pins on the lower housing that prevent the bearing from slipping away
• Static radial load: at 0° angle compensation = 50 kN; at 9° = 25 kN

Durable in any weather: plain bearings in the PV tracker

Tracking systems from TecnoSun Solar Systems AG score highly in terms of cost efficiency thanks to their low installation height. For the traction ring, the company was looking for bearings that are low-maintenance and can withstand decades of operation in all weather conditions. They found what they were looking for at igus®: Dry-running iglidur ® P bearings are maintenance-free, insensitive to dirt and extreme weather conditions and can easily withstand high loads caused by snow masses.
