The committee responsible for this document is ISO/TC 4, Rolling bearings, Subcommittee SC 4, Tolerances, tolerance definitioncluding GPS). This fifth edition cancels and replaces the fourth edition ( ISO 492:2002 ), which has been technically revised.
· 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
· basic load ratings of roller bearings are defined in ISO 281 and can be calculated by Equation 2.1 and 2.2. The baa listed in the dimension tables of NSK needle bearings are calculated in accordance with ISO, but amended with development of
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.
