A piston () having a piston shaft (), a ball head () at one end of the piston shaft (), and a slider shoe () mounted to the ball head (), wherein the ball head () has a through channel (), the slider shoe () has a sliding surface () and a through hole () in communication with an end of the through channel (), and a plastic material () is arranged in a gap between the slider shoe () and the ball head () and forms an inner coating () of the through hole (). The production of such a piston should be facilitated. To this end a sealing surface () is arranged at the end of the through channel () wherein the sealing surface () surrounds the opening of the through channel () into the through bore () and an inner diameter of the sealing surface () is smaller than an inner diameter of the inner coating () of the through bore ().
