The aim of the invention is to produce a multi-piece piston with a sufficient shaft length in a simple manner. To achieve this, the lower part (1) has the following characteristics: - it consists of two halves (2,3) that have been welded or soldered together, - the parting plane (4) between the two halves (2,3) runs in the pressure-counter-pressure direction - the two halves (2,3) consist of extruded or forged steel the diameter of the shaft (5) in the direction of the pin is reduced in relation to the diameter of the piston, in the manner a box piston.
