ISO NNU4921V Bearing

Tolerances

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 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 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 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.
