5. Overall Weight Parameters

Carbon steel balls use the standard carbon steel density (7.83g/cm³), ensuring uniform density and dense structure. The same specification steel balls have consistent weight, no deviation, and no heavy-light differences, with a high consistency in batch weight. Small diameter carbon steel balls are light in weight and roll sensitively, suitable for light transmission, small counterweights, and precise positioning applications. Medium to large diameter carbon steel balls are heavy and stable, suitable for heavy equipment counterweights, static loads, and mechanical balance structures. Precision weight parameter tables are available for all specifications, facilitating customer structural design, equipment selection, packaging calculations, and foreign trade documentation.

6. Load-bearing and compressive properties

Carbon steel balls have a uniform spherical structure with a regular pressure-bearing surface, exhibiting excellent compressive, extrusion-resistant, impact-resistant, and fatigue-resistant properties. High-grade carbon steel balls treated with quenching and hardening have a high surface hardness and sufficient core toughness, effectively resisting long-term static loading, high-frequency rolling extrusion, and instantaneous mechanical impact. After being subjected to stress, they are less prone to issues such as indentation, deformation, cracking, and peeling.

Standard precision carbon steel balls are suitable for light to medium-duty conventional load-bearing conditions, meeting the needs of general hardware and light industrial equipment; high precision and high hardness carbon steel balls are suitable for medium-heavy industrial applications, capable of withstanding long-term stable mechanical pressure with superior wear and pressure resistance compared to ordinary iron components.
