Competitive Advantages
Material Superiority
GCr15 steel offers exceptional hardness and fatigue resistance due to its 1% carbon and 1.5% chromium composition, outperforming standard carbon steel balls in lifespan.
Precision Manufacturing
Our G10 tolerance (±0.025mm) ensures consistent performance in high-speed applications where even micron-level variations affect efficiency.
Enhanced Durability
Through-bulk hardening and precision grinding, our balls maintain dimensional stability under extreme loads (up to 3,500 MPa).
Rigorous Quality Control
Every production batch undergoes:
- Spectrometer analysis for material composition verification
- Coordinate measuring machine (CMM) inspection for dimensional accuracy
- Surface roughness testing with profilometers
- 100% hardness testing with Rockwell scale verification
- Salt spray testing for corrosion resistance (optional)
We maintain ISO 9001:2015 certification with full traceability from raw material to finished product.
Frequently Asked Questions
Q: What makes GCr15 superior to stainless steel for bearing applications?
A: GCr15 provides higher load capacity and fatigue life due to its optimized carbon-chromium matrix, though it requires proper lubrication to prevent corrosion.
Q: Can you supply balls outside the 13mm–25mm range?
A: Yes, we produce custom diameters from 3mm to 50mm with the same G10 precision standards.
Q: What packaging options are available for bulk orders?
A: We offer anti-rust vacuum packing (100–500 pcs/box), 25kg steel drums, or custom palletized solutions.
Q: How do your G10 balls compare to G20 or G40 grades?
A: G10 balls have 2–4x tighter tolerances than G20 (±0.05mm) and G40 (±0.1mm), reducing vibration in precision mechanisms.
