This product is aimed at large hydraulic applications where the cylinder barrel cannot be economically or technically produced from standard honed tube or common pipe stock. A forged barrel blank offers better adaptability for heavy wall sections, custom sizes, and demanding service conditions. It is usually supplied for further boring, honing, and precision machining according to hydraulic system requirements. For large hydraulic cylinder applications, customers usually focus on wall-thickness reserve, boring allowance, straightness potential, and the ability of the forged blank to support later honing and precision machining. A forged barrel is particularly valuable when the cylinder size exceeds standard tube capability or when thicker sections and project-specific geometry must be maintained under heavy service conditions. The supply condition can be coordinated with the intended machining route so that the customer receives a blank suitable for rough boring, heat treatment, honing, and final dimensional finishing.
