This standard specifies the symbolic representation of parameters such as dimensions, dimensional tolerances, precision, rated load, and service life of rolling bearings. These symbols are mainly used in standards and documents for rolling bearings, but also in other printed materials such as product brochures, diagrams and brochures.
