The ISO dimensional system specifies the following dimensions for rolling bearings: bore diameter, d, outside diameter, D, width, B, (or height, T) and chamfer dimension, r, and provides for the diameter to range from a bore size of 0.6 mm to an outside diameter of 2500 mm.

Greatest radial distance, in any equatorial plane, between the smallest circumscribed sphere and the greatest inscribed sphere, with their centres common to the least square sphere centre. Ball lot. -. Defines quantity of balls manufactured under conditions presumed uniform and which is considered as an entity.

ISO 15243: classifies different modes of failure occurring in service for rolling bearings made of standard bearing steels. For each failure mode, it defines and describes the characteristics, appearance and possible root causes of failure. It will assist in the identification of failure modes based on appearance.
