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.

Scope. Standardization of all types and all sizes of bearing elements based on the principle of rolling motion, including the lubrication, their accessories, application and identification and

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

For the ISO, JIS, and DiN standards, bearings with standard accuracy are classified as class 0. This is then followed by class 6.

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.

DIN 616 describes dimension plans for radial and axial bearings. An overview of ISO and DIN rolling bearing standards is given in DIN 611:2010-05.
