Slide bearings are machine components that support rotating or oscillating shafts through sliding movement on a bearing surface. Unlike rolling bearings, they have no rolling elements. Friction is reduced by a lubricating film, usually generated by external lubrication (e.g. oil or grease). Slide bearings are particularly quiet, compact, and resistant to dirt and shock loads. They are often used in continuously operating machines, such as electric motors, turbines, generators and ship propulsion systems.
