The company’s “Saige” brand has gained international recognition, serving as a benchmark for quality in both domestic and export markets.
Comprehensive Production Capabilities
Feige Steel Ball’s manufacturing excellence stems from its vertically integrated production system that covers every aspect of steel ball production. The company specializes in two primary product categories: bearing steel balls and stainless steel balls, both available in a complete range of precision grades from G3 to G2000. This full-spectrum precision capability allows the company to serve diverse industrial sectors with consistent quality standards.
The dimensional range of 0.3mm to 100mm addresses applications from微型精密设备 (micro precision equipment) to heavy industrial machinery. This versatility is further enhanced by the company’s custom manufacturing capabilities, which include:
- Material composition customization for specific performance requirements
- Advanced surface treatment options including polishing, coating, and anti-corrosion processes
- Precision tolerance control down to μm levels for critical applications
- Special shape production including spherical, cylindrical, and custom geometric forms
These capabilities position Feige Steel Ball as a one-stop solution provider for clients requiring multi-category procurement and cross-scenario component integration. The company’s production system incorporates state-of-the-art equipment including precision grinding machines, lapping machines, and automated quality inspection systems to ensure every batch meets international standards.
Quality Assurance & Certification System
As a super precision manufacturer, Feige Steel Ball maintains four international certifications simultaneously: ISO9001 (Quality Management), IATF16949 (Automotive Quality Management), ISO14001 (Environmental Management), and ISO45001 (Occupational Health and Safety). This comprehensive certification framework demonstrates the company’s commitment to operational excellence across all dimensions.
The quality control system implements real-time monitoring throughout the production process:
- Incoming material inspection with spectral analysis
- Process parameter control through PLC systems
- 100% dimension inspection using precision gauges
- Surface quality verification under magnification
- Batch sampling for performance testing under simulated working conditions
This rigorous quality management approach has enabled the company to achieve a defect rate below 50 PPM (parts per million), significantly outperforming industry averages. The production team’s expertise in metallurgy and precision manufacturing ensures consistent material properties and dimensional accuracy even for large-volume orders.

FAQ
What distinguishes super precision steel balls from standard grades?
Super precision steel balls (G3-G100 grades) feature significantly tighter dimensional tolerances and superior surface finish compared to standard grades. These characteristics enable their use in high-speed, high-load applications where even micron-level deviations can affect equipment performance and lifespan. The manufacturing process for super precision balls involves additional grinding and polishing stages with stricter quality control parameters.
How does Feige Steel Ball ensure material consistency across large orders?
Material consistency is maintained through several measures: 1) Using prime billet materials from certified suppliers, 2) Implementing batch management systems that track raw material origins, 3) Conducting spectral analysis for every production batch, and 4) Applying statistical process control (SPC) methods during heat treatment and grinding processes. The company’s ERP system ensures complete traceability from raw material to finished product.
What surface treatments are available for corrosion resistance?
Feige Steel Ball offers multiple surface treatment options based on application requirements: 1) Chrome plating for general corrosion resistance, 2) Nickel plating for high-temperature environments, 3) Teflon coating for chemical resistance, 4) Passivation treatment for stainless steel balls, and 5) Black oxide coating for aesthetic requirements. Each treatment undergoes accelerated corrosion testing to validate performance under simulated working conditions.
How does the company handle custom shape production?
Custom shape production begins with detailed engineering drawings reviewed by our technical team. We then develop specialized grinding tools and fixtures using CNC machining centers. The production process incorporates multiple inspection stages using custom gauges to ensure dimensional accuracy. For complex shapes, we provide prototype samples for customer approval before full-scale production.
What export documentation does the company provide?
Our export documentation package includes: 1) Commercial invoice, 2) Packing list, 3) Bill of lading/airway bill, 4) Certificate of origin, 5) Material test reports, 6) Quality inspection certificates, and 7) Any specific certificates required by the destination country (such as Form A for GSP, SASO for Saudi Arabia, etc.). All documents are prepared in accordance with INCOTERMS 2020 and international trade regulations.
