Shandong Donge Steel Ball Co., Ltd manufactures chrome steel balls from high‑carbon chromium steel, identified as GCr15, AISI 52100 or SUJ2. The catalogue covers diameters from 1.0 mm up to 50.8 mm, with grades ranging from G10 to G1000 to suit varying load requirements. Each ball is produced in accordance with ISO 3290, ensuring dimensional consistency and material quality. The heat‑treatment process yields a hardness of approximately HRC 60‑63, delivering the wear resistance needed in precision equipment.
Industry practice classifies standard grades for bearing balls between G10 (soft) and G1000 (extra hard), with most applications using G50‑G200. Typical surface roughness is Ra 0.2 µm and dimensional tolerance follows ISO 3290: ±0.001 mm for sizes up to 10 mm and ±0.005 mm for larger diameters. These parameters meet the specifications of automotive and aerospace OEMs that demand low run‑out and long service life. Donge’s product line aligns with these norms while offering a broad size spectrum for replacement and new‑build projects.
The balls are employed in rolling‑element bearings, valve seats, and precision instrumentation across automotive, aerospace and heavy‑machinery sectors. Buyers can request flexible MOQ and benefit from export packaging in sealed paper bags or wooden crates, with shipment terms such as FOB or CIF available. As a harbor‑trust tier supplier, Donge provides ISO certification documents on demand, allowing importers to verify compliance before finalising the purchase.

When ordering from Shandong Donge Steel Ball Co., Ltd, importers should first request the ISO 3290 certificate and a mill test report confirming the GCr15 composition. Obtaining a sample batch for dimensional and surface finish verification is advisable to ensure the supplied grade meets project requirements. Verify the supplier’s bank details and request trade references to reduce financial exposure.
Logistics should be coordinated around the preferred Incoterms, with FOB Qingdao or CIF to the destination port commonly offered. As lead times are not published, the buyer must obtain a confirmed production schedule before committing to shipment. Payment structures are usually a 30 % deposit with the balance payable against documents, but terms should be clearly defined in the sales contract.
Quality control can be reinforced by arranging an independent inspection focusing on hardness, tolerance and surface roughness before loading. Request inspection certificates, hardness test results and surface finish charts from the supplier. Maintaining comprehensive documentation, including the mill test report, packing list and certificate of origin, will streamline customs clearance and protect the buyer’s interests.
