Piston engine with a housing in which a shaft ( 19 ) is rotatably mounted in two pivot bearings of which at least one pivot bearing has an inner ring ( 26 a) which is seated without radial clearance of motion on a supporting region ( 28 ) of a bearing section ( 19 c) of said shaft ( 19 ). In order to prolong the working life of the at least one pivot bearing, the axial length of the supporting region ( 28 ) corresponds to a central region (a) of the bearing section ( 19 c), a radial clearance of motion being disposed, at the two outer regions (b, c), between said outer regions (b, c) and the inner ring ( 26 a).
