A ball bearing is often a type of rolling element bearing which employs balls to sustain separation amongst moving parts of a bearing. These ball bearings are used to minimize and minimalise the rotational friction plus the axial and radial loads. Ball bearings obtain this by using no less than two races, which contain the balls and transfer any loads by way of the balls. At times one with the races is fixed into location.

As one on the races turns/rotates the balls rotate at the same time and since the balls are rolling they have a significantly reduce coefficient of friction. It’s the little surfaces on the balls between the races that permit them to possess a reduced load capacity for their size. The low cost of making the ball bearing makes it significantly less expensive than other kinds of bearing.
There are several diverse kinds of ball bearings mechanisms readily available for many applications and these can include things like:
o Aircraft bearing: A term frequently applied to bearings used by the aircraft market or the Air Force.
o Airframe bearing: A bearing created for use within the control systems and surfaces of aircraft.
o Angular contact bearing: A variety of ball bearing whose internal clearances and ball race locations as for example to result in a definite contact angle between the races and also the balls when the bearing is used.
o Anti friction bearing: A frequently used term for rolling element bearing.
o Ball bearing: A bearing using balls as the rolling element.
o Ball cage: A device that partly surrounds the balls and travels with them.
o Ball complement: Number of balls used inside a ball bearing.
o Cone: Inner ring of tapered roller bearing.
o Double row bearing: A bearing of two rolling elements.
Uses for ball bearings are vast and some common applications can incorporate:
o Automobile wheels
o Washing machine drum bearings
o Bicycle wheels
o Dental equipment
o Machine tools; drills, centre lathes, milling machines etc.
Other forms of bearings have also been developed such as fluid bearings. These fluid bearings usually do not use steel balls just like the extra standard ball bearing, but rather assistance the bearings load on a thin layer of liquid or gas. This type of bearing is usually used in laptop or computer really hard drives.
Other fluid bearings involve; foil bearings, Air bearings, and journal bearings.
