The paper studies the effectiveness of new techniques of stabilizing the geometrical parameters of bearing rings in comparison with the thermal stabilization. Processing of bearing rings is made on a special machine in a liquid medium where the ultrasonic vibrations are excited. It is shown that roundness of the rings after ultrasonic stabilization is substantially lower than after the heat treatment.

The article describes the process efficiency of ultrasonic mechanical stabilization of details in comparison with the conventional thermal treatment. It is shown that ultrasonic treatment enhances the productivity and quality of manufactured details. As a result of the proposed stabilizing treatment the relaxation of residual stresses, the required geometry, such as waviness and ovality, as well as necessary mechanical properties are ensured.
