Abstract: An axial bearing device is provided for the cylinder barrel in an axial piston machine, particularly of so-called bent-axis type, i.e. with the axis of the barrel inclined to the axis of the drive disk. The barrel is rotatably journalled in a housing, which is open at one end, and adapted to be resiliently urged by means of a spring member against a valve disk at the other end of said housing, which is closed. The spring member comprises an elongated leaf spring which at one end is fixed at a position on the inside of the housing and at the other engages a bearing ring located in a raceway radially outwardly of the mouths of the cylinder bores at the end of the cylinder barrel remote from said valve disk.
