  2. Wire race bearing - Wikipedia

    en.wikipedia.org/wiki/Wire_race_bearing

    A wire race bearing is a rolling-element bearing, where the balls or rollers run on races resembling loops of wire. 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 ...

  3. Ball bearing - Wikipedia

    en.wikipedia.org/wiki/Ball_bearing

    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.

  4. Ball (bearing) - Wikipedia

    en.wikipedia.org/wiki/Ball_(bearing)

    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.

  5. ABEC scale - Wikipedia

    en.wikipedia.org/wiki/ABEC_scale

    Illustration of bearing tolerances (in micrometers) for a bearing with a 20 mm inner diameter. For illustration, the figure shows the differences in tolerance per ABEC class in micrometers (μm) for a 20 mm inner diameter bearing. [1] A 20 mm ABEC 7 bearing only has a 5 μm tolerance window, whereas an ABEC 1 has twice as wide a tolerance.

  6. American wire gauge - Wikipedia

    en.wikipedia.org/wiki/American_wire_gauge

    AWG is colloquially referred to as gauge and the zeros in thick wire sizes are referred to as aught / ˈ ɔː t /. Wire sized 1 AWG is referred to as "one gauge" or "No. 1" wire; similarly, thinner sizes are pronounced "x gauge" or "No. x" wire, where x is the positive-integer AWG number. Consecutive AWG wire sizes thicker than No. 1 wire are ...

  7. Race (bearing) - Wikipedia

    en.wikipedia.org/wiki/Race_(bearing)

    In the case of ball bearings, the bearing has inner and outer races and a set of balls. Each race is a ring with a groove where the balls rest. The groove is usually shaped so the ball is a slightly loose fit in the groove. Thus, in principle, the ball contacts each race at a single point.

  8. Bearing (mechanical) - Wikipedia

    en.wikipedia.org/wiki/Bearing_(mechanical)

    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.

  9. Slewing bearing - Wikipedia

    en.wikipedia.org/wiki/Slewing_bearing

    Slew ring bearing. A slewing bearing or slew[ing] ring (also called a turntable bearing) is a rotational rolling-element bearing that typically supports a heavy but slow-turning or slowly-oscillating loads in combination (axial, radial and moment loads), often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis (yaw) windmill.
