Nowadays, minimum lubrication is imperious in mechanical systems and its upper limit is the “dry condition”. Similarly, materials, manufacturing processes, heat treatments, mounting and maintenance of these systems are constrained on high competitive cost matrix that constitutes a complex scenario of the residual stresses and material strength points-of-view. The aim of this investigation was measure the cyclic evolution of residual stresses on a race of a 51100 thrust rolling bearing manufactured of DIN 100Cr6 steel after tests in a tribometer under a dry condition. The Sin²ψ XRD method was used for mapping these residual stresses. Three zones on circumferential and radial directions of the rolling race, after 104, 105 cycles and at collapse were selected for the evaluation and compared to the new (“as received”) condition. Central tendency and dispersion of the measurements are discussed and compared to published data. Keywords: Residual stresses, X-Ray Diffraction, Structural Integrity, Tribology.
