Bearings are essential components used in various mechanical systems to reduce friction and enable smooth rotation or linear movement. They consist of a rolling element, such as balls or rollers, enclosed within an outer and inner ring. Bearings are widely used in industries such as automotive, aerospace, and manufacturing. They provide support and stability to rotating or moving parts, ensuring efficient operation and reduced wear and tear. With different types and sizes available, bearings play a crucial role in enhancing the performance and longevity of machinery and equipment.
