Apart from the standard accuracies defined by DIN/ISO, higher accuracies are specified Tolerances for bore and outside diameters, ring and bearing width.

iso 281:2007 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

The boundary dimensions of commonly used bearings mostly conform to the organizational concept of ISO, and the bearing numbers of these standard bearings.

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.

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.

You can find more information on ISO 492 and ISO 199, and the changes that have been made to their previous editions, on the SKF e-learning platform. There are three common tolerance classes for SKF ball and roller bearings: Minimum standard for all SKF ball and roller bearings. Tighter tolerances than Normal. Tighter tolerances than class 6.
