Send us your requirements:

• Diameter (mm/inch) + quantity
• Grade (G5–G100)
• Material (GCr15 or GCr15SiMn)
• Intended application / bearing type
• Packaging needs (bulk / tube / customized)

Common Applications:

• Automotive: Bearings, steering systems, transmission components
• Aerospace: Critical mechanisms requiring precision and reliability
• Manufacturing: Grinding, polishing, mixing processes
• Machinery: Valves, pumps, couplings (corrosion resistance extends equipment life)

Packing and Shipping:

Typical lead time for 10,000 pcs of G5 bearing balls (GCr15) depends mainly on whether the size is in stock and whether you need custom inspection/packaging.

• If in stock (common sizes): usually 3–7 days to pack + ship-out
• If not in stock / need production: typically 15–25 days after order confirmation (size/grade confirmed)
• If custom packaging + full inspection report required: add about 2–5 days
• If the diameter is large (e.g., > 50 mm) or very small micro sizes: it can extend to around 20–35 days due to grinding/polishing time and tighter yield control for G5
