❓ FAQs About G10 Bike Bearing Chrome Steel Balls

Will these G10 steel balls fit my bike’s wheel bearings?

Most bike wheel bearings use sizes between 3mm~9mm—our 1mm~9.525mm G10 chrome steel balls cover nearly all standard bike bearing sizes. Check your bike’s manual for exact diameter needs, or contact us for help!

What does “G10 precision” mean for bike bearings?

G10 is a high-precision grade—these steel balls have minimal size deviation (±0.002mm) and smooth surfaces. This reduces bearing noise, extends lifespan, and ensures smoother bike rides vs. lower-grade (G16/G20) balls.

Is GCR15 chrome steel durable for outdoor bike use?

Yes! GCR15 chrome steel has excellent corrosion resistance and hardness (HRC 60-65), making it resistant to rain, dirt, and wear—perfect for outdoor bike bearings that face harsh conditions.

Can I return these steel balls if they don’t fit my bike?

You can return unused G10 chrome steel balls within 7 days for a refund or replacement (return shipping paid by buyer). Please contact us first to confirm return details—note: used balls or electronic components are non-returnable.
