Abstract: The invention relates to an arrangement for the axial bearing of the drilling machine. The drilling machine thereby comprises a body (6), a percussion device (1) fitted in the body, and a rotation bushing (3) functioning as a rotating means of a shank (2) positioned on an axial extension of the percussion device. Furthermore, an axial bearing is fitted within the body (6) for receiving the axial forces exerted on the body (6) through the shank (2). In order to provide resilience, the axial bearing is arranged to be displaceable in the axial direction under the influence of a pressure medium acting thereon. To resiliently receive a percussion impulse reflected from the rock during the drilling process, the pressure and volume flow of the pressure medium of the axial bearing is adjustable so that the position (Y) of the axial bearing is between the extreme positions (0, DELTA X) of the axial bearing under the normal operating conditions of the drilling machine.
