Bearing sleeves play a crucial role in supporting rotating shafts while allowing them to move freely with minimal friction. These components are often used in situations where traditional rolling element bearings may not be suitable due to factors such as space constraints, environmental conditions, or cost considerations. Bearing sleeves are available in various configurations, including flanged, split, and solid designs, to accommodate different shaft sizes and mounting requirements. Additionally, they can be lubricated with oils or greases to further reduce friction and ensure smooth operation over extended periods. Despite their relatively simple design, bearing sleeves are integral components in many machinery and equipment, contributing to the overall efficiency and reliability of mechanical systems.
