    Abstract: The present invention relates to a sliding bearing arrangement (1) for supporting a shaft (10) in a support element (11), comprising an inner bearing part (12) with a sliding surface (13) and comprising an outer bearing part (14) with a sliding surface (15), whereas when the shaft (10) is rotating around an axis (16), the sliding surface (13) of the inner bearing part (12) performs a sliding movement relative to the sliding surface (15) of the outer bearing part (14). According to the invention, at least one of the sliding surfaces (13, 15) features at least one recess area (17) which is extending in a circumferential direction of the surface (13, 15) over a circumferential angle (α1, α2) and which is extending over at least 50% of the axial length of the sliding surface (13, 15), and the recess area (17) is dimensioned in such a way that over the recess area (17) the clearance distance between the inner bearing part (12) and the outer bearing part (14) is increased.
