Steel Ball
The offering comprises steel balls produced in three material grades: chrome steel AISI 52100, stainless steel 440C and carbon steel, each conforming to GB308‑2002, ISO3290‑1998 and AFBMA standards. Diameter options span from 0.8 mm (1/16 in) up to 50.8 mm (2 in), and the catalogue lists precision grades from G5 to G1000, covering a broad selection of tolerance levels for diverse applications. The supplier cites compliance with DIN 5401‑93 and provides the balls in reinforced cartons or drums for safe transport.
In the bearing industry, AISI 52100 chrome steel is favoured for its high hardness, typically HRC 60‑66, while 440C stainless steel offers superior corrosion resistance for food‑grade or marine environments. Standard practice for precision balls limits sphericity deviation to ±0.002 mm and surface roughness to Ra ≤ 0.25 µm, ensuring reliable performance in high‑speed rotations. Typical bulk packaging accommodates up to 25 kg per container, allowing efficient loading for large‑scale orders.
Customers such as automotive component makers, ball‑valve manufacturers and precision instrument producers often source these balls for high‑load bearing assemblies and motion‑control systems. The supplier’s export‑ready packaging meets international trade requirements, and test certificates can be supplied on demand. Buyers are encouraged to confirm the exact minimum order quantity, anticipated lead time and preferred Incoterm before finalising any purchase.

Sourcing Steel Ball from Qingdao Zhongnuo Steel - China Import Guide
Prior to placing an order, importers should request a detailed material test report confirming the exact alloy composition, verify the grade tolerance required for their equipment, and obtain the latest copies of the GB308‑2002 and ISO3290‑1998 certificates from the supplier. Clarifying the minimum order quantity and any special packaging needs at this stage prevents unexpected delays or additional freight charges.
The balls are exported from the Qingdao port area; typical Incoterms such as FOB Qingdao or CIF can be negotiated, but the final term must be confirmed with the supplier. Common payment methods include T/T against documents or a confirmed Letter of Credit, and buyers should agree on any advance payment percentages before contract signing.
Quality control normally involves third‑party inspection of hardness, dimensional accuracy and surface finish. The supplier can issue a mill test certificate and, if required, arrange an independent laboratory report. Keeping these documents on file aids customs clearance and ensures the product meets the buyer’s performance specifications.
