It is a question of a multi-part piston more especially for use in double acting cylinder actuators. The piston has two piston halves that are mounted on a piston rod so as to be symmetrical about a contact surface between them. Each piston half has a metallic inner member with a radial anchoring projection, as for example in the form of a flange. On the inner member there is a molded casing of synthetic resin. Each piston half has a piston seal arranged in a circumferential groove in the outer surface of the casing.
