N1 - Funding Information: The authors would like to thank the LUIS CLUSTER SYSTEM which allowed which allowed the extensive simulations. FELIX PRIGGE, whose merit is the development and improvement of the simulation model. NORBERT BADER, TIMM COORS and GABRIEL CALDERON SALMERON, for the hours of professional, technical and talkative discussions. And lastly MATTHIAS STAMMLER, who strongly advanced research on oscillating bearings through his work. This document is the results of the research project ( 0325918 ) partly funded by the Federal Ministry of Economics and Technology (Germany).

N2 - Small oscillating amplitudes (~0. 1°) and larger (> 1°) can both lead to wear, w hich complicates the evaluation of the operating conditions. In this work, a simulation model is used to discuss critical amplitudes. The parametric study, which includes 125 simulations, shows the effect of load and coefficient of friction on the frictional work density for amplitudes ranging from 0.1 to 2.5°. The study concludes that the frictional work density increases with the oscillating amplitude up to a certain point, where it becomes almost constant in relation to the amplitude. This point is reached when the amplitude is so large that a continuous overlapping of the contact zone no longer occurs. It is precisely this point that marks the critical oscillation amplitude.
