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]
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.
Auburn Ball Bearing's primary product, their Auburn Four-Point-Cone-Contact Ball Thrust Bearings, incorporates an exclusive "V" groove raceway, designed to distribute the load evenly over the balls as they travel on four points of contact, creating a straight line rolling effect and decreasing the amount of friction created by a full contact ...
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. However, a load on an infinitely small point would cause infinitely high contact pressure. In practice, the ball deforms (flattens) slightly where it contacts each race, much as a tire flattens where ...
I suggest reinstating the example of bearing series usage and how it may vary between manufacturers, i.e. that a deep groove ball bearing with 45mm bore could be described as either 6909 or as 61909. Also I suggest removal of citation requests for series included in standard (i.e. ISO) tables.
The Winsted Precision Ball Company was founded in 1949 with the sole purpose of manufacturing high-precision balls for the use in miniature precision ball bearings. Acquired by Barden Corporation in the 1960s, [ 26 ] WPBC is not a separate legal entity, but a department of the Barden Corporation's Danbury location.
