Solar plants operate under extreme environmental conditions. igus® offers plain and spherical plain bearings as well as energy chains that precisely meet these requirements. They impress with their long service life, durability and low costs. Application scenarios for plain bearings are for instance solar tower power plants, parabolic trough power plants or the axis of rotation for panel adjustments. Dirt-repellent and lubrication-free spherical bearings are very suitable for solar plants. Energy chains with a defined torsional stop and minimum bend radius can however be found in photovoltaic systems.
▲ Tech up
Absorption of high static (wind) loads (up to 50kN)
Angular compensation with spherical bearing (up to 9°)
Guaranteed service life of 25 years (72 years almost wear-free, simulated in the igus® laboratory at 1.5 tonnes)
Lubrication-free, therefore no maintenance required
Simple and quick assembly
Dirt-repellent and temperature-resistant plain bearings are used in the photovoltaic tracking system of Conergy AG.
Customer-specific special parts are used for the rotary movement of the solar panels, which are cost-effective and maintenance-free.
