This paper shows that small variations of the dimensions and quality of manufactured parts may lead to great changes of the size of the contact zones and the bearing ratio curves thus increasing the stress applied to the material. In consequence, the Hertz’s critical tension is modified and the ultimate stress or fatigue limit of the material may be exceeded. An industrial case is used to illustrate this assertion.
