The present invention concerns an arrangement for the mounting of a piston (2) onto a piston rod (4) for a hydraulic or pneumatic piston-cylinder unit (1), which piston (2) is provided with a penetrating hole (7) with an internal thread (8) and a first axial groove (9), which groove (9) is intended to be aligned with a second axial groove (22) arranged in association with a section (21) of the piston rod (4) when the piston (2) is mounted onto the piston rod (4), and in that the grooves (9, 22) after the alignment form an indentation (26) intended to receive a securing means (28). The end (16) of the piston rod (4) comprises a peripheral opening (24) for a locking means (25) that prevents the securing means (28) from being displaced from the indentation (26). The invention concerns also a method for the mounting of a piston onto a piston rod. |
