【 摘 要 】

In order to achieve a normal behavior of the bearing during exploitation, it is necessary to study the characteristics of the rolling elements material. The experiments are meant to determine the mechanical characteristics of the material used in ball bearing manufacturing (e.g. tensile strength, fatigue). The trials conducted have been split into two different categories: in a first stage statically tests have been performed, in which the bearing ball has been tested for compression until breakage using a special device developed for this purpose. The second stage has been dedicated to dynamical tests, using a specially designed fatigue test machine for bearing balls. The experimental results have been statistically worked out, acquiring conclusive results for the trials performed.
