Rigorous Quality Control Process
Every production batch undergoes comprehensive testing:
- Material certification (chemical composition analysis)
- Dimensional verification (laser micrometers)
- Hardness testing (Rockwell C scale)
- Surface inspection (microscopic examination)
- Noise testing (bearing assembly evaluation)
- Sample destructive testing (fatigue analysis)
We maintain ISO 9001:2015 certification with full traceability from raw material to finished product.
Frequently Asked Questions
Q: What makes GCr15 superior to standard carbon steel balls?
A: GCr15 contains 1.5% chromium which significantly improves hardness, wear resistance, and contact fatigue strength compared to standard carbon steels.
