GB/Z 32332.2-2015

This standard provides guidance on calculating the modified rating life of rolling bearings using a systems approach that accounts for fatigue stresses from the entire bearing arrangement, including lubrication, contamination, and mounting conditions. It is applied in mechanical engineering and industrial machinery design, particularly for applications requiring high reliability and precise life predictions, such as in automotive transmissions, wind turbines, and heavy equipment. The standard serves as a technical reference for engineers performing durability assessments and life-cycle optimization of bearing systems.
