Abstract
A hydrostatic axial piston machine () has a cylinder barrel () with a plurality of piston bores having pistons () fastened in an articulated manner to a drive flange (). For articulated fastening of the pistons () to the drive flange (), ball joints () are provided that are formed by a spherical cap-shaped receptacle socket () in an end surface () of the drive flange () and a ball head () that is operatively connected with the piston (). The receptacle sockets () are each in the form of hemispheres that extend to the ball equator, and on one end surface () of the drive flange (), in the vicinity of the receptacle sockets (), there is a retaining web () that extends beyond the ball equator of the hemisphere to grip the ball head () at an angle of greater than 180°.
