solar Solutions for the solar industry UV-resistant, lubrication and maintenance-free plastics for longer life

Your technical innovator and cost reducer, Thomas Preißner Phone: +49-2203 9649-115 Email: tpreissner@igus.de www.igus.eu/solar The requirements placed on plain and spherical bearings for systems that are used to obtain energy from sunlight are very varied. Extreme temperatures and weathering by wind, water, dirt and dust push metallic bearings to their very limits. The dry-tech® bearing technology from igus® can be used even in extreme surroundings and under high loads. The polymer bearings need no lubrication of any kind and contribute towards a longer service life for all types of...

igus® research and test labo- It all started with an idea. When Günter Blase founded the company in his Cologne garage in 1964, igus® consisted of no more than a small injection moulding machine and the belief in the future of the material "plastic". Tribologically optimised polymers, according to the basic igus® vision, was the key to solving the "eternal" problems of moving applications. The traditional "solution", the lubrication with oils or greases, has negative consequences, such as high maintenance, environmental pollution and machine failure. The Tribo-optimised (friction-optimised)...

25 years guarantee on igus® products made of igumid G* In general, all products made of igumid are characterised by a long service life and permanent resistance to corrosion, even when exposed to the weather. Why should you prefer igus® plastics to other plastics? Continuous exposure to UV radiation, changing temperature cycles (day/night), frequent moisture level changes (absorption/drying), fatigue due to continuous mechanical stress etc. are factors that weaken and damage the plastic, change it structurally and alter its mechanical and tribological properties. igus® has proven the...
