Import Chrome Steel Ball — Buy in Bulk from Supplier in China

Guagdong Steel Ball Co., Ltd supplies chrome steel balls ranging from 0.5 mm to 250 mm in diameter. Each ball is forged from high‑carbon chromium steel, equivalent to grades GCr15 or AISI 52100, and heat‑treated to achieve a hardness of about HRC 60‑63. The manufacturing process follows ISO 3290 tolerances, delivering consistent dimensional accuracy across the size range. These attributes give the balls strong resistance to wear and corrosion, suitable for demanding industrial environments.

In the bearing industry, standard grades for chrome steel balls are classified from G10 to G1000, with the most common being G50‑G200 for general‑purpose bearings. Typical surface finish is Ra 0.2 µm, and dimensional tolerance is ±0.001 mm for diameters up to 10 mm, widening to ±0.005 mm for larger sizes. Such specifications meet the requirements of automotive and aerospace manufacturers that demand precise run‑out and long service life. Guagdong’s product line aligns with these industry norms while offering a broad size spectrum for replacement and new‑build projects.

The balls are widely used in rolling‑element bearings, valve seats, and precision machined components for automotive, aerospace and heavy‑machinery sectors. Buyers can request flexible minimum order quantities and benefit from secure packaging in paper bags or wooden crates, with shipment options including FOB or CIF terms. As an imported‑tier supplier with a harbor trust rating, Guagdong provides ISO certification documentation on request, enabling buyers to verify compliance before import.
