Durable, maintenance-free components for renewable energies

Generating energy, especially from renewable sources, requires reliable, durable technology solutions. In the process, the various systems are often exposed to extreme environmental conditions such as UV radiation, temperature fluctuations, strong winds, dirt and dust, which they have to withstand for years.

Tailored to the specific system, we offer you special solutions made of high-performance polymers, which can help you improve your technology, optimise your system and reduce costs.

Advantages of igus products:

Free from lubrication and maintenance
UV-resistant
Insensitive to dirt and dust
Weatherproof
Corrosion-free
Long, predictable service life

Requirements for the bearings of single-axis solar trackers

The bearings of single-axis solar trackers are exposed to adverse environmental conditions over a period of 25 years, ideally without failures and with as little maintenance as possible. The bearings' load profile includes UV radiation, high and low temperatures as well as dirt, sand and dust. Under these conditions, a pillow block bearing made of high-performance plastic with incorporated lubricant proves its worth.

Lower operating costs with lubrication-free pillow block bearings in single-axis tracking systems

on our igubal ESQM pillow block bearings in its single-axis tracking systems. As they require neither lubrication nor maintenance, unlike metal bearings, the customer can reduce operating costs. Thanks to the low-friction movement and ability to compensate for misalignment, system performance is significantly improved.
