A 1045 piston rod is a high-strength mechanical component widely used in hydraulic cylinders, pneumatic systems, and industrial machinery. It serves as the main force-transmitting element between the piston and the external mechanism, converting hydraulic or pneumatic pressure into controlled linear motion. Made from high-quality AISI 1045 medium carbon steel, this piston rod is known for its excellent strength, toughness, and machinability, making it one of the most popular choices for heavy-duty applications in construction, agriculture, and manufacturing industries.
