Frequently Asked Questions

Q: What makes GCr15 superior to standard steel for precision balls?

A: GCr15 contains chromium (1.3-1.6%) for enhanced hardness and wear resistance, with optimized carbon content (0.95-1.05%) for strength and durability.

Q: How does G10 tolerance compare to other grades?

A: G10 (±0.025mm) offers tighter dimensional control than standard grades (typically G20 or G40), ensuring smoother operation in precision mechanisms.

Q: Can you provide custom sizes outside the 13mm-25mm range?

A: Yes, we offer custom manufacturing for specialized applications. Contact us to discuss your specific requirements.

Q: What surface treatments are available for GCr15 balls?

A: Options include polishing, grinding, superfinishing, and various anti-corrosion coatings to meet application needs.

Conclusion

For industrial applications demanding precision, reliability, and longevity, GCr15 G10 steel balls (13mm-25mm) outperform standard 29/64″ (11.509mm) balls in nearly every technical aspect. The combination of high-grade bearing steel, tight G10 tolerances, and rigorous quality control makes these components ideal for critical applications where performance cannot be compromised.

When selecting steel balls for your application, consider not just the initial cost but the total cost of ownership, including maintenance, replacement frequency, and system performance.
