The precision and robustness of bearing supports make a decisive contribution to achieving maximum efficiency in a tracking system. High rigidity is required for the precise alignment of the reflectors and collectors to the sun and, thus, accurate concentration of the sun’s rays. The bearings must not only withstand local weather conditions, but also high forces and moments, for example during sudden gusts of wind.

 

Various bearing types can be considered, depending on the type and design of power plant. The bearings are categorized according to their suitability for azimuth and elevation (A/E) axes below:
