Omfattning
This International Standard specifies methods of calculating the basic dynamic load rating of rolling bearings
within the size ranges shown in the relevant ISO publications, manufactured from contemporary, commonly
used, high quality hardened bearing steel, in accordance with good manufacturing practice and basically of
conventional design as regards the shape of rolling contact surfaces.
This document also specifies methods of calculating the basic rating life, which is the life associated with 90 %
reliability, with commonly used high quality material, good manufacturing quality and with conventional
operating conditions. In addition, it specifies methods of calculating the modified rating life, in which various
reliabilities, lubrication condition, contaminated lubricant and fatigue load of the bearing are taken into account.
This International Standard does not cover the influence of wear, corrosion and electrical erosion on bearing
life.
This document is not applicable to designs where the rolling elements operate directly on a shaft or housing
surface, unless that surface is equivalent in all respects to the bearing ring (or washer) raceway it replaces.
Double-row radial bearings and double-direction thrust bearings are, when referred to in this document,
presumed to be symmetrical.
Further limitations concerning particular types of bearings are included in the relevant clauses.
