Eliminate middleman costs by sourcing directly from the Kangda manufacturing line. We specialize in high-precision AISI 52100 chrome steel balls, optimized for bearing assemblies and heavy-duty industrial applications.
The GCr15 Bearing Steel Ball (equivalent to AISI 52100) is the industry standard for high-load bearing applications. Characterized by a high carbon and chromium content, these spheres offer exceptional hardness (HRC 60-66) and wear resistance. Unlike standard carbon steel, GCr15 maintains structural integrity under extreme rotational stress.
For procurement managers seeking consistent spherical precision and material purity, our large-diameter chrome steel balls (31mm-47mm) provide the stability required for wind turbines, automotive hubs, and heavy mining machinery.

Purchasing Manager, Germany
"The consistency of the GCr15 balls from Kangda is impressive. We switched suppliers last year and have seen a significant reduction in QA rejections. Stable lead times are a huge plus."
Bearing Manufacturer
Supply Chain Lead, USA
"Sourcing 45mm chrome steel balls directly from the factory helped us control costs without compromising on the hardness requirements. Highly recommended for bulk buyers."
Industrial Equipment Firm
Procurement Director, Brazil
"Packaging is robust and withstands sea freight perfectly. The rust protection oil they use is effective. A reliable partner for our annual contracts."
As a direct manufacturer, our MOQ typically starts at 500kg - 1000kg depending on current stock levels and production schedules. This ensures the most competitive factory-gate pricing.
Yes, every batch is accompanied by a full Mill Test Certificate showing chemical composition (C, Cr, Mn, Si) and physical properties to ensure compliance with AISI 52100 standards.
All GCr15 balls are washed, dried, and coated with anti-rust oil before being packed in VCI paper and sealed in plastic bags within standard wooden boxes or drums.
Absolutely. Our facility is equipped to produce precision grades ranging from G10 for high-precision bearings to G1000 for grinding media applications.
Standard lead time is 15-25 days for production. However, for common sizes like 45mm, we often maintain safety stock for faster dispatch.
Yes, we provide free samples for quality verification. Clients are typically responsible for the courier shipping costs.
