A piston rod has a first end and a second end, the first end being connected to the piston and the second end protruding outside the cylinder tube in the region of the second end of the cylinder tube. A bottom element is located in the region of the first end of the cylinder tube, and it is designed and arranged to seal the first end of the cylinder tube and the interior of the cylinder tube. An oil connection element is located in the region of the bottom element, and it is designed and arranged to allow for oil entering and exiting the interior of the cylinder tube through the oil connection element. A pivot unit includes a thread, and it is designed and arranged to be connected to the cylinder tube by the thread, the pivot unit including at least one pivot element being designed and arranged to support the hydraulic cylinder in a pivotable way. A ring includes a thread, and it is designed and arranged to be connected to the cylinder tube by the thread and to contact the pivot unit. The pivot unit and the ring are designed to be arranged on the cylinder tube in locking engagement in each desired turning position about the cylinder axis with respect to the bottom piece and to the oil connection element.
