Macro shot of metallic ball bearings coated with grease. The surface is shiny and polished, reflecting light with a mixture of blue and gold tones. The bearings are round and embedded in a circular metal raceway, showing textured grooves and lubricant droplets. The close-up highlights the precision engineering of the components, indicating their use in machinery to reduce friction and allow smooth motion. The image captures the intricate details of the metal surface and the distribution of the lubricant.
