Abstract
An arrangement for a piston-and-cylinder unit is disclosed. The arrangement includes a cylinder member and a piston member movable therein, to which a piston rod is connected. The cylinder member includes a barrel pipe and closure portions at each end of the cylinder member, with the closure portion at one end exhibiting a bush. The bush is provided with a through bore for the piston rod and is enclosed by an end portion of the barrel pipe. The end portion is bent radially inwards, towards the piston rod and over a first circumferential surface of the bush. The bush is provided with a collar portion exhibiting an external second circumferential surface of the bush, enclosing the circumference of the piston rod and extending axially beyond the inwardly bent portion. The inwardly bent portion of the barrel pipe terminates in a circumferential edge located adjacent to a positive corner of the bush formed between the first circumferential surface and the second circumferential surface.
