Descriptions of Hydraulic Piston Rod

Our hydraulic piston rods are engineered from premium medium-carbon steel, specifically grades 1045/1050, renowned for its remarkable strength, toughness, and exceptional wear resistance. Each rod undergoes a meticulous production process that begins with precise machining of high-quality carbon steel, ensuring optimal performance in hydraulic and pneumatic applications.

To enhance durability, Baokun‘s piston rods are subjected to induction hardening, significantly increasing surface hardness and providing resistance against bending, cracking, and abrasion. Following the hardening process, we employ precision grinding techniques to achieve a smooth, uniform surface, critical for efficient operation.

Our piston rods receive a durable chrome plating. This chrome layer not only offers outstanding corrosion resistance but also provides a polished finish that reduces friction, ensuring seamless operation in various industrial settings.

Applications of Hydraulic Piston Rod

Typical applications of hydraulic piston rods include agricultural equipment, hydraulic cylinders, hoists and other lifting equipment. They are also used in machine tools, and mining and earth-moving equipment, ensuring durability and efficiency in demanding industrial environments.

Benefits of Chrome Plating For Piston Rods

Chrome plating on piston rods offers several essential benefits that enhance performance and longevity. It provides superior wear and corrosion resistance, significantly extending the lifespan of the rods in high-friction environments. The smooth surface reduces friction, improving operational efficiency and energy consumption. Additionally, chrome plating ensures better load distribution, minimizing deformation risk. Its polished appearance enhances aesthetics, while the non-porous surface simplifies cleaning and maintenance. Chrome plating also withstands high temperatures, making it suitable for demanding applications. Overall, this treatment is a cost-effective solution that leads to improved reliability and reduced maintenance costs for industrial machinery.
