In the global industrial supply chain, precision steel balls serve as critical components in bearings, automotive parts, aerospace equipment, and medical devices. Changzhou Feige Steel Ball Co., Ltd., a leading manufacturer based in China’s advanced manufacturing hub, has established itself as a benchmark for quality and innovation in the steel ball industry. With 18,000㎡ production facilities and 4,000 tons annual capacity, the company specializes in delivering full-category precision steel ball solutions that meet the most demanding international standards.

Comprehensive Product Range Covering All Precision Grades
Feige Steel Ball’s core product line includes bearing steel balls and stainless steel balls with precision grades ranging from G3 to G2000, covering the complete spectrum of industrial requirements. The size availability spans from ultra-miniature 0.3mm balls for medical devices to large 100mm balls for heavy machinery applications. This extensive range enables the company to serve diverse markets including:
- Automotive components (ABS sensors, bearings, gearboxes)
- Aerospace equipment (navigation systems, precision instruments)
- Medical devices (endoscopes, surgical tools)
- Industrial machinery (conveyor systems, robotics)
- Consumer electronics (precision connectors, switches)
The company’s “Saige” brand has gained international recognition for consistently delivering balls with exceptional roundness (<0.1μm for G3 grade), surface finish (Ra≤0.01μm), and dimensional accuracy (±0.001mm tolerance for critical applications). These specifications are verified through advanced testing equipment including roundness measuring instruments, surface profilers, and hardness testers.
Customization Capabilities: Beyond Standard Solutions
Understanding that modern industries often require specialized components, Feige Steel Ball has invested heavily in custom manufacturing capabilities. The company’s non-standard production services cover:
| Customization Parameter | Available Options |
|---|---|
| Material Composition | Chrome steel (GCr15), stainless steel (304/316/440C), carbon steel, brass, ceramic |
| Surface Treatments | Polishing, grinding, passivation, black oxide coating, nickel plating |
| Precision Grades | G3-G2000 (ISO 3290 standard) |
| Special Shapes | Spherical, cylindrical, truncated, satellite balls |
This flexibility has enabled the company to develop specialized solutions for unique applications. For example, their ceramic balls with 68 HRC hardness are used in high-temperature environments up to 800°C, while their nickel-plated balls provide superior corrosion resistance for marine applications. The engineering team works closely with clients during the development phase, providing material selection guidance, prototype testing, and production optimization.

Quality Assurance System: Four International Certifications
Feige Steel Ball’s commitment to quality is demonstrated through its comprehensive certification portfolio including ISO 9001 (quality management), IATF 16949 (automotive industry), ISO 14001 (environmental management), and ISO 45001 (occupational health and safety). The production process follows strict protocols:
- Raw material inspection with spectrometer analysis
- In-process quality control at every manufacturing stage
- 100% dimensional verification for precision grades
- Batch sampling for hardness and corrosion resistance tests
- Final inspection report with traceability code for each order
The company’s laboratory is equipped with advanced testing instruments capable of measuring geometric tolerances down to 0.0001mm. This rigorous quality control system ensures that every ball meets the specified requirements before shipment, with defect rates maintained below 50 PPM (parts per million) for standard products and 10 PPM for precision grades.
Export-Oriented Services: Simplifying Global Supply Chains
As an established export manufacturer serving clients in 45 countries, Feige Steel Ball has developed a comprehensive service system to facilitate international trade:
- Compliance Documentation: Complete set of export documents including certificate of origin, material test reports, and quality certificates
- Custom Packaging: Plastic tubes, cardboard boxes, or steel drums with anti-rust coating, customizable with client logos
- Logistics Support:
- After-Sales Service: 24-hour technical support, free replacement for quality issues, lifetime process consultation
Coordination with freight forwarders for FOB/CIF/DDP terms, container loading supervision
The company’s export team consists of professionals fluent in English, German, and Spanish, ensuring smooth communication throughout the order process. They maintain stock of standard sizes for immediate shipment while offering flexible MOQs (minimum order quantities) for custom products – as low as 10,000 pieces for basic specifications and 50,000 pieces for precision grades.
FAQ
What is the minimum order quantity for custom-sized steel balls?
Our MOQ depends on the specification complexity. For standard sizes with basic requirements, we accept orders from 10,000 pieces. For precision grades (G10 and above) or special materials, the MOQ starts at 50,000 pieces. We recommend sharing your exact requirements with our sales team for a precise quotation.
How do you ensure the consistency of ball quality across large orders?
We implement strict batch control systems where each production run uses raw materials from the same heat lot. Our automated sorting machines can process up to 500,000 balls per hour while maintaining ±0.001mm dimensional accuracy. Every batch comes with a quality certificate showing actual measurement data from our testing lab.
What lead time should I expect for custom steel ball production?
Standard sizes in stock can ship within 3 working days. For custom orders, the lead time is typically 15-25 days depending on specification complexity. This includes 3-5 days for prototype approval (when required), 7-10 days for mass production, and 3-5 days for quality inspection and packaging.
Do you provide samples before bulk production?
Yes, we offer free samples (up to 100 pieces) for standard products to verify quality. For custom specifications, we charge a prototype fee that’s refundable after the first bulk order. Sample delivery usually takes 5-7 working days via international courier.
