This report provides a comprehensive analysis of journal bearing design for a heliostat within a sustainable system framework. It covers bearing diameter selection using load-speed charts and Sommerfeld Number calculations, force and pressure considerations, and the determination of maximum allowable specific wear rate and PV limit. Material selection is justified based on desirable characteristics like low friction and high compressive strength, with SAE 11 Babbitt and Nylon identified as suitable options. The report also includes friction torque calculations and optimization strategies to ensure a 25-year lifespan with minimal wear. Finally, a GSM-based monitoring and prevention system is proposed to detect and report any abnormalities in heliostat operation, enhancing system reliability. The design process is iterative, optimizing for machinability and performance, ensuring a balance between theoretical calculations and practical implementation.
