Plain bearings for single-axis tracking systems directions. The 150-meter collector chains can be aligned with the course of the sun from east to west to an accuracy of a tenth of a millimeter. The rod ends are equipped with manganese phosphated radial spherical plain bearings with a steel/steel sliding contact surface. This special surface treatment protects the material from wear and reduces friction. The spherical plain bearings’ inner rings have a width of 70 millimeters, a cylindrical bore with a diameter of 110 millimeters and a convex outer slideway, while the 160millimeter outer...
