Product Range: Comprehensive Solutions for Diverse Applications
Our core product portfolio focuses on two main categories: bearing steel balls and stainless steel balls. Within these categories, we offer an extensive range of precision grades from G3 to G2000, covering the complete spectrum of industrial requirements. The size range we produce spans from 0.3mm micro balls for precision instruments up to 100mm large balls for heavy-duty machinery applications.
This comprehensive standard range is complemented by our specialized customization capabilities. We understand that different industries and applications have unique requirements that standard products may not fully address. Therefore, we offer tailored solutions including:
- Custom material compositions beyond standard bearing steel and stainless steel
- Specialized surface treatments for enhanced performance characteristics
- Precision tolerance adjustments to meet exacting specifications
- Non-standard shapes and structures for specialized applications
Material Expertise and Grade Selection
Our high carbon chromium bearing steel balls are manufactured using carefully selected raw materials that meet stringent international standards. The typical composition includes 1.0% maximum silicon, 0.5% maximum manganese, 0.025% maximum phosphorus, 0.025% maximum sulfur, and 1.30-1.65% chromium content. This specific formulation provides the optimal balance of hardness, wear resistance, and fatigue strength required for demanding bearing applications.
For stainless steel balls, we offer both 300 series and 400 series options to accommodate different corrosion resistance requirements and cost considerations. Our material experts work closely with clients to determine the most suitable grade based on the specific operating environment, load conditions, and performance expectations of each application.
Quality Assurance: Multiple Certifications and Rigorous Testing
Quality is the cornerstone of our manufacturing philosophy. Our four international certifications form the foundation of our quality management system, but we go beyond compliance by implementing additional internal controls and testing procedures at every production stage. From raw material inspection to final product verification, each steel ball undergoes multiple quality checks to ensure it meets our exacting standards.
Our IATF16949 certification is particularly significant for automotive industry clients, as it represents compliance with the most stringent quality management requirements in this sector. This certification covers not only our production processes but also our supply chain management, product development, and continuous improvement practices, providing comprehensive assurance of our capability to serve automotive applications reliably.
| Quality Parameter | Testing Method | Acceptance Criteria |
|---|---|---|
| Surface Roughness | Profilometer measurement | ≤0.01μm for G3-G10 grades |
| Hardness | Rockwell hardness tester | 60-66 HRC for bearing steel |
| Roundness | Roundness measuring instrument | ≤0.125μm for G3 grade |
| Surface Defect | Visual inspection under magnification | No visible defects at 40X magnification |
