The present invention relates to a sliding bearing arrangement for supporting a shaft in a support element, comprising an inner bearing part with a sliding surface and comprising an outer bearing part with a sliding surface, whereas when the shaft is rotating around an axis, the sliding surface of the inner bearing part performs a sliding movement relative to the sliding surface of the outer bearing part. According to the invention, at least one of the sliding surfaces features at least one recess area which is extending in a circumferential direction of the surface over a circumferential angle (α1, α2) and which is extending over at least 50% of the axial length of the sliding surface, and the recess area is dimensioned in such a way that over the recess area the clearance distance between the inner bearing part and the outer bearing part is increased.
