  2. Ball bearing - Wikipedia

    en.wikipedia.org/wiki/Ball_bearing

    Although bearings had been developed since ancient times, the first modern recorded patent on ball bearings was awarded to Philip Vaughan, a Welsh inventor and ironmaster who created the first design for a ball bearing in Carmarthen in 1794. His was the first modern ball-bearing design, with the ball running along a groove in the axle assembly. [1]

    Thus, the worldwide success story of the ball bearing begins in Schweinfurt. Later, 1883 is officially declared the year in which the company was founded. 1890 - On July 17, Fischer received the patent for his ball grinding machine from the Kaiserliches Patentamt.

  4. 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.

  5. Wire race bearing - Wikipedia

    en.wikipedia.org/wiki/Wire_race_bearing

    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. Due to the design wire race bearings are commonly called '4-point-contact' bearings. [1]

    The book covers various subjects, including bearing and shear stress, experimental stress analysis, stress concentrations, material behavior, and stress and strain measurement. It also features expanded tables and cases, improved notations and figures within the tables, consistent table and equation numbering, and verification of correction ...

  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. Rolling-element bearing - Wikipedia

    en.wikipedia.org/wiki/Rolling-element_bearing

    A sealed deep groove ball bearing. In mechanical engineering, a rolling-element bearing, also known as a rolling bearing, [1] is a bearing which carries a load by placing rolling elements (such as balls, cylinders, or cones) between two concentric, grooved rings called races.

    SUGGESTED ADDITION: Philip Vaughan was a Welsh inventor and ironmaster who patented the first design for a ball bearing in Carmarthen in 1794.[1] His design ran along a track in an axle assembly, known as a ball race, thus originating the modern ball bearing design.[2] PER WIKIPEDIAHoohoolian 22:31, 19 June 2013 (UTC)
