Silicon nitride bearing balls, in diameters ranging from 1 to 20mm. Bearing balls are special highly spherical and smooth balls, most commonly used in ball bearings, but also used as components in things like freewheel mechanisms. The balls themselves are commonly referred to as ball bearings. [1] This is an example of a synecdoche.
Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races. Common ball bearing designs include angular contact, axial, deep-groove, and preloaded pairs.
Roller bearings may use just two races, but ball bearings typically use three or four races. Wire race bearings can be large yet lightweight and with small profile and good precision. Wire races have little intrinsic structure and must be adequately supported by the bearing housing. Balls, rollers or even cross rollers are used as rolling elements.
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.
