ISO ISO/TC 4 Rolling bearings
· 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 ISO 281:2007 Rolling bearings — Dynamic load
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.
ISO 15243:2017 classifies different modes of failure occurring in service for rolling bearings made of standard bearing steelss and describes the characteristics, appearance and possible root causes of failure. It will assist in the identification of
· 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,
