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

Solar plants are exposed to extreme environmental conditions. igus® offers plain and spherical plain bearings, as well as energy chains, that operate successfully in solar applications and their environments. igus® products have long service lives, are very durable and are low in cost. Application scenarios for plain bearings include solar tower power plants, parabolic trough power plants or the axis of rotation for panel adjustments. Dirt-resistant and self-lubricating spherical bearings in particular are very suitable for solar plants. Energy chains with a defined torsional stop and minimum bend radius, however, can be found in photovoltaic systems.
