“…This indicates that the development of cracks is a consequence of the repeated loads applied, that is, it has a fatigue-like character. Another important indicator is the conditional probabilities of the appearance of at least one crack at any point in the cross section at a given depth [17,18,19,20]. To determine them, we consider the cross section of the core of the crosspiece and a metal layer of unit thickness located at the i-th depth from the surface of the core.…”

“…The combination of these extreme values of pressure and velocity, together with the low antifriction steel properties, from which the rollers and races are produced, creates a very hard operating mode and high axle loads to be borne by the axle box. As a result, the wear of the roller ends and the race edges occurs intensively, especially in the initial operating period of new bearings [13,14].…”

“…Taking into account the fact that the radius of the mating circle is significantly less than the radius of the generatrix, the tolerance should be accepted: R2 = 300 ± 20 mm. The ordinates of the circles described by the nominal and limit radii are presented in table 2 [7].…”
