A ball bearing. A bearing is a machine element that constrains relative motion to only the desired motion and reduces friction between moving parts.The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts.
A ball bearing is a rolling-element bearing that uses balls to reduce friction and support loads. Learn about the common designs, materials and history of ball bearings, from ancient times to modern applications.
Fluid bearings are bearings that use a thin layer of pressurized liquid or gas to support the load and reduce friction, wear and vibration. They can be classified into fluid dynamic (hydrodynamic) and hydrostatic bearings, and are used in high load, high speed or high precision applications.
