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. Plain bearings typically handle only lower speeds, rolling element bearings are faster, followed by fluid bearings and finally magnetic bearings which are limited ultimately by centripetal force overcoming material strength. Watch makers produce “jeweled” watches using sapphire plain bearings to reduce friction thus allowing more precise time keeping. Precision ball bearings are used to reduce friction in every rotating parts of automobiles, machine tools and others. Thin bearings facilitate design downsizing and weight saving. Ball bearings will be used for many years to come, because they are very simple and have become very inexpensive to manufacture. The race contains the bearings, and as one of the objects that rest on the bearing moves, the balls rotate, allowing for the near frictionless encounter between the borne object and the bearing.
