Various rolling contact fatigue tests have demonstrated that white structures are caused by hydrogen penetration.
Accordingly, the Court construes 'cam' to mean 'a structure that makes sliding or rolling contact with the tibial post as the knee bends.'
Aimed at the wheel/rail wear problem, many researches have been carried out from the wheel/rail rolling contact theory, experiment and simulation methods.
The cylinder barrel runs on a thin film of fluid instead of using rolling contact bearings.
In this study, thus, it is assumed that the rolling contact fatigue life of an automotive wheel bearing also has a maximum value at a constant hardening depth.
The pump has no bearings that come into contact with process fluids, no internal sliding or rolling contact and no rotor-to-rotor contact.0x20

Through train and track dynamic analysis, it is possible to evaluate how modifications in train and/or track affect several factors such as riding comfort, vehicle or track accelerations, derailment risk, rolling contact fatigue, rail stresses, and rail deflection.
The rolling contact fatigue (RCF) occurred during the rolling contact of a contact pair due to the cyclic force in the contact zone and caused the crack formed on the material surface or subsurface to extend, so material fatigue damage failure occurred [3].
Hardness in the range 59-66 HRC has shown to be positively correlated with rolling contact fatigue life; greater hardness is associated with reduced wear on the surface.
