A ball bearing can be a variety of rolling element bearing which employs balls to sustain separation involving moving parts of a bearing. These ball bearings are used to lessen and minimalise the rotational friction along with the axial and radial loads. Ball bearings realize this by using no less than two races, which contain the balls and transfer any loads through the balls. Sometimes one from the races is fixed into place.

As one of the races turns/rotates the balls rotate at the same time and mainly because the balls are rolling they have a a lot lower coefficient of friction. It's the smaller surfaces of the balls amongst the races that let them to possess a reduced load capacity for their size. The low cost of creating the ball bearing makes it less high priced than other varieties of bearing.
There are several various sorts of ball bearings mechanisms available for different applications and these can incorporate:
o Aircraft bearing: A term typically applied to bearings used by the aircraft industry or the Air Force.
o Airframe bearing: A bearing developed for use within the control systems and surfaces of aircraft.
o Angular contact bearing: A kind of ball bearing whose internal clearances and ball race locations as including to lead to a definite contact angle in between the races plus the balls when the bearing is used.
o Anti friction bearing: A usually used term for rolling element bearing.
o Ball bearing: A bearing using balls because the rolling element.
o Ball cage: A device that partly surrounds the balls and travels with them.
o Ball complement: Number of balls used in 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 a few standard applications can contain:
o Automobile wheels
o Washing machine drum bearings
o Bicycle wheels
o Dental gear
o Machine tools; drills, centre lathes, milling machines etc.
Other sorts of bearings have also been developed for example fluid bearings. These fluid bearings usually do not use steel balls like the more conventional ball bearing, but as an alternative help the bearings load on a thin layer of liquid or gas. This kind of bearing is generally used in pc hard drives.
Other fluid bearings consist of; foil bearings, Air bearings, and journal bearings.
