· Standardization of all types and all sizes of bearing elements based on the principle of rolling motion, includingication and standardization of spherical plain bearings, i.e. plain bearings with spherical contact surface. ISO/TC 4/SC 4
ISO 492:2014 specifies dimensional and geometrical characteristics, limit deviations from nominal values, and tolerance valuesace (except chamfers) of radial rolling bearings. The nominal boundary dimensions are defined in ISO 15, ISO 355 and ISO 8443.
· ISO Dimensional system and bearing numbers 1.1 ISO Dimensional system The boundary dimensions of rolling bearings, width, and chamfer dimensions have been standardized so that common dimensions can be adopted on a worldwide scale. In Japan,
Tolerance classes and the corresponding values for certain tolerance characteristics are specified in ISO 492 (for radial bearthese standards were aligned with general ISO GPS (Geometrical Product Specification) standards such as ISO 1101 and ISO 5459.
ISO 281:2007 specifies methods of calculating the basic dynamic load rating of rolling bearings within the size ranges shown irdance with good manufacturing practice and basically of conventional design as regards the shape of rolling contact surfaces.
