How are ball bearings measured
Bearing balls are manufactured to a specific grade, which defines its geometric tolerances. The grades range from 2000 to 3, where the smaller the number the higher the precision. Grades are written "GXXXX", i.e. grade 100 would be "G100". Lower grades also have fewer defects, such as flats, pits, soft spots, and cuts. The surface smoothness is measured in two ways: surface roughness and waviness. WebBoundary dimensions are the main dimensions of a bearing (fig. 1 and fig. 2). They comprise: The bore diameter (d) The outside diameter (D) The width or height (B, C, T or …
