Welcome to the H+B portfolio since August 2023, THE PISTON ROD
The piston rod is part of a cylinder. It guides the piston in a cylinder, i.e. supports movements in machines, commercial vehicles, in the automotive sector, etc. The piston rod is surface-coated with a chromium or chromium/nickel layer for better resistance (used mostly in an oxidative environment or in tougher outdoor applications such as construction machinery). The piston rod also serves as a sealing surface between the power operated (pressure) area of the cylinder and the outside environment. The area of application is the area in which the movements of machine parts are power-assisted.
The medium that moves the piston is usually hydraulic oil, in pneumatic cylinders compressed air or a mixture of inert gases.
Another area of application for piston rods are linear guides, in which a carriage is moved linearly (on a longitudinal axis), e.g. in machine tools.
