The calculation methods pertain to the fatigue life of the bearings. Other mechanisms of failure, like wear or microspalling (ed single row radial ball bearings, subjected to radial and axial load, and with radial clearance and tilt taken into account.
Values: ISO 492 (table 1, table 2, table 3) Normal Values: ISO 492 : Internal clearance For additional information → Internal O 5753 1 , except for d < 10 mm Values are valid for unmounted bearings under zero measuring load. Permissible misalignment
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.
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.
