ABSTRACT:
A piston having a body member made from plastic material adapted for mounting to a piston rod for axial movement with the piston rod in a hydraulic cylinder under high working pressure conditions is disclosed. The plastic piston body member has a first axial end portion, an opposite second axial end portion, an outer circumferential surface portion adapted to be located in intimate relation with a cylinder wall of the hydraulic cylinder when the piston is positioned for axial movement therein, and an inner peripheral surface portion defining a centrally located axially extending aperture through the body member adapted for cooperatively receiving a mounting portion of the piston rod, one of the axial end portions being positioned to abut an adjacent shoulder of the piston rod when the mounting portion of the piston rod is located in a fully received position in the aperture. When the mounting portion of the piston rod is in the fully received position in the aperture of the body member, the inner peripheral surface portion of the body member is adapted to be located in intimate relation with an outer mounting surface of the mounting portion, and the body member is cooperatively engageable with a retainer for securing the body member to the piston rod.
