| Summary: | This review examines various strategies to enhance the energy efficiency of roller bearings by reducing frictional torques from multiple sources: roller rolling resistance, sliding friction at roller ends, lubricant agitation, interactions with bearing cages, and frictional losses in seals. The review shows that recent advancements emphasise the significance of design variables, lubrication strategies, and geometrical optimisations. Surface roughness, precision coatings, oil flow alternations, and bearing geometry also significantly influence frictional torque. This review highlights the potential for significant reduction of frictional torque through the implementation of energy-efficient seal designs as well as the importance of precise friction torque measurement methodologies. These insights underscore the need for ongoing research and development to further improve roller bearing efficiency and reliability across various applications. |
