UV-resistant, lubrication-free and maintenance-free plain and spherical bearings for solar technology

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.
