Abstract: A linear-drive cylinder actuated by a pull means or by a pressure medium has a cylinder tube, in which a piston is guided axially displaceably. The movement of the piston is guided outward via force-transmission means. The cylinder tube is closed on the end face by means of a closing plug. Both the cylinder tube and the closing plug each have a transverse bore. A fastening means, such as, for example, a holding tube or a bolt, passes through the mutually aligned transverse bores, so that the closing plug is secured axially in the cylinder tube.

Abstract: A linear drive without a piston rod, which has a laterally slotted guide tube closed on the end faces and a piston mounted so as to be slidably displaceable therein, is provided with a sealing band and with separate profile elements engaging the sealing band. The sealing band extends from one end of the guide tube along its longitudinal slot to its other end. In order to hold the sealing band in the longitudinal slot, separate profile elements are arranged in the longitudinal slot. The profile elements cause the sealing band to engage the guide tube.
