Extra Large 70mm Solid Carbon Steel Ball For Ultra Heavy Duty Industrial

The 70mm solid carbon steel ball is an extra-large, heavy-duty spherical component forged from premium carbon steel, with an impressive diameter of 70mm. It integrates the exceptional strength and durability of carbon steel with the inherent structural stability of a spherical shape, making it an ideal choice for ultra-heavy-duty industrial, large-scale engineering, and specialized application scenarios. Its substantial size grants it outstanding load-bearing capacity, while the spherical design ensures uniform force distribution, catering to the demands of extreme-load and critical structural support applications.

Premium carbon steel is selected as the raw material for the 70mm solid carbon steel ball. This material boasts exceptional mechanical properties, including high toughness, optimal hardness, and favorable cost-effectiveness, making it perfectly suited for applications that demand extraordinary load-bearing capacity and prolonged durability in harsh environments.

1. Heavy-Duty Forming: The manufacturing process begins with heavy-duty forming techniques such as hot forging or precision casting to shape the initial spherical structure. This ensures the ball's core structure is dense and uniform, laying a solid foundation for withstanding extreme loads.
2. Precision Grinding and Polishing: After forming, the balls undergo meticulous grinding to achieve the exact 70mm diameter. A subsequent high-precision polishing treatment refines the surface, reducing surface roughness to Ra≤1.6μm. This smooth surface not only improves performance in rotational or sliding applications but also enhances corrosion resistance, even in challenging working conditions.
3. Strict Quality Control: Each 70mm solid carbon steel ball undergoes rigorous quality inspection using advanced testing equipment. Dimensional accuracy, surface finish, material density, and mechanical properties are thoroughly checked to ensure every product meets stringent standards and can reliably perform in ultra-heavy-duty environments.

1. Large-Scale Crushing and Milling Equipment: In ultra-heavy-duty industrial machinery like large crushers, ball mills, and heavy-duty rolling mills, the 70mm solid carbon steel balls act as key components in grinding systems and load-bearing rollers. They withstand extreme pressures and facilitate efficient material processing, ensuring the machinery operates continuously under heavy loads.
2. Heavy Machinery Frames and Supports: They are employed as critical structural support components in large equipment frames, hydraulic presses, and heavy stamping machines, providing stable support and absorbing intense forces generated during operation.

1. Bridges and Large Structures: In infrastructure projects such as bridges, large-scale steel structures, and heavy-duty platforms, these 70mm steel balls are used in bearing systems and movable joints, enabling smooth movement while supporting massive structural loads.
2. Marine and Offshore Equipment: They find application in marine and offshore equipment such as shipyard cranes, offshore platforms, and heavy-duty winches, contributing to the stable operation and safety of these critical marine structures in harsh saltwater environments.
