Technical details and manufacturing context for Rod Assembly

Definition
The rod assembly is a critical component within articulation cylinders, serving as the load-bearing element that connects the piston to external machinery. It transmits linear force from the hydraulic or pneumatic pressure acting on the piston to perform work, such as lifting, pushing, or positioning loads in industrial equipment. In articulation cylinders specifically, it enables the pivotal movement between connected sections.
Working Principle
The rod assembly moves linearly within the cylinder barrel, driven by pressure differentials across the piston. It converts fluid energy into mechanical force, with seals preventing leakage and bearings or bushings minimizing friction during extension and retraction cycles.
Common Materials
Chrome-plated steel
