An important role in the further operation of rolling bearings is played by the shape of the grooves of the ball bearing rings. That is why it is necessary to pay special attention to the formation of their profile. To study the shape of the trough, we studied a batch of ball bearing rings using the method of measuring the size of the stamps. Since the bearing also works with small radial loads, it is necessary to press in not only at right angles. Additionally, we propose to strengthen the effect of indentation. From the experiments it can be seen that there is a different distribution of stresses along the contact area for bearings of the same size. Based on this, it can be argued that the accuracy of the machining process is insufficient. Therefore, there is a need to improve the accuracy of shaping the profile of ball bearing rings by advanced technologies. To do this, we propose to use imitation completion. After this procedure, after conducting experiments, one can again see how the characteristics of the raceway profile of ball bearings have qualitatively changed, and, accordingly, their durability.
