Plain Bearing

Plain bearings, also known as sleeve or sliding bearings, are the simplest type of bearings that enable motion through direct surface-to-surface sliding contact without rolling elements. They consist of a shaft rotating or sliding within a cylindrical bore or housing, relying on lubrication to minimize friction and wear while supporting high radial loads at low to moderate speeds. These compact, cost-effective components excel in applications like engines, pumps, and construction machinery where quiet operation and high load capacity in dirty environments matter
