AB Heat treatment of rolling bearings components is an indispensable part of their production and also is the unavoidable item of the price in calculating of bearings. Technological process of heat treatment must be created rationally and in addition to the required hardness must also ensure the dimensional precision of bearings components. For predicting of the development of thermal and mechanical properties during heat treatment (for simulation only quenching) we used the simulation software SYSWELD from ESI Group. In addition to the microstructure and hardness the simulation results also consist of values of deformations and stresses in each axis (X, Y, Z), which cause distortions during the heat treatment. The results can be used for the selection of material, editing of shape bearings with respect to heat treatment and proposal of the optimal technological process of heat treatment. The results were compared with real measured values of hardness, but especially with values of deformations in each axis.
