In modern industrial manufacturing, the demand for high-performance wear-resistant steel balls continues to grow across various sectors. As a professional steel ball manufacturer with 18,000㎡ production facilities in Changzhou, China, Changzhou Feige Steel Ball Co., Ltd. has established itself as a leading supplier in the global market. Our annual production capacity of 4,000 tons and comprehensive certification system (ISO9001, IATF16949, ISO14001, ISO45001) ensure consistent quality for demanding industrial applications.
Comprehensive Product Range for Diverse Applications
Our core product lineup includes two main categories: bearing steel balls and stainless steel balls, both available in full-spectrum precision grades from G3 to G2000. The size range covers 0.3mm micro balls for precision instruments up to 100mm large balls for heavy machinery applications. This comprehensive coverage enables us to serve multiple industries including automotive, aerospace, medical equipment, and industrial machinery.
The bearing steel balls (GCr15 material) demonstrate excellent hardness (HRC 60-66) and wear resistance, making them ideal for high-speed rotating applications. Our stainless steel balls (304/316/440C grades) offer superior corrosion resistance for chemical processing, food machinery, and marine applications. Each product undergoes strict quality control including dimensional inspection, surface roughness measurement, and material composition analysis.
Customized Solutions for Special Requirements
Understanding that standard products cannot meet all industrial needs, we offer extensive customization capabilities through our non-standard steel ball production line. Our engineering team works closely with clients to develop solutions for unique requirements including:
- Special material compositions (e.g., high-carbon chromium alloy, manganese steel)
- Precision surface treatments (polishing, grinding, passivation)
- Tight tolerance control (±0.001mm for ultra-precision applications)
- Complex geometric shapes (flat, oval, satellite, truncated)
- Custom packaging solutions (vacuum packaging, anti-rust coating, bulk containers)
A recent project for a European automotive supplier demonstrates our customization capabilities. The client required 8mm stainless steel balls with 0.002mm tolerance for transmission systems. Our production team developed a specialized grinding process and implemented 100% inspection using optical sorting equipment to ensure zero defect delivery.
Technical Specifications Comparison
The following table illustrates the key differences between our standard bearing steel balls and stainless steel balls:
| Parameter | Bearing Steel Ball | Stainless Steel Ball |
|---|---|---|
| Material Grade | GCr15 (AISI 52100) | 304/316/440C |
| Hardness | HRC 60-66 | HRC 50-58 (440C) |
| Corrosion Resistance | Standard (requires coating) | Excellent (316 grade) |
| Magnetic Property | Magnetic | Non-magnetic (304/316) |
| Recommended Applications | High-speed bearings, automotive components | Chemical equipment, food processing, medical devices |

FAQ
What is the minimum order quantity for customized steel balls?
Our minimum order quantity starts from 10,000 pieces for standard sizes and 5,000 pieces for customized specifications. For large-diameter balls (above 50mm), the MOQ is 1,000 pieces due to production complexity.
How do you ensure product consistency for large orders?
We implement strict quality control throughout production: raw material inspection, in-process monitoring, and final inspection before packaging. For orders exceeding 100,000 pieces, we assign dedicated production lines and quality engineers to maintain consistency.
What is your lead time for standard products?
Standard products in common sizes (1-20mm) typically ship within 7-10 working days after order confirmation. For larger sizes or special grades, the lead time extends to 15-20 working days depending on production schedule.
Can you provide samples before mass production?
Yes, we offer free samples (up to 100 pieces) for quality verification. For customized products, we provide prototype samples within 5-7 working days after receiving technical drawings and specifications.
What payment terms do you accept for international orders?
Our standard payment terms are 30% deposit by T/T before production and 70% balance before shipment. For regular clients with established credit, we offer flexible terms including LC at sight and OA payment options.
How do you handle quality complaints after delivery?
We maintain complete traceability for all products through batch numbering. In case of quality issues, our after-sales team responds within 24 hours and provides solutions including replacement, refund, or technical support based on investigation results.
What certifications do your products have?
Our manufacturing facilities maintain ISO9001, IATF16949 (automotive quality), ISO14001 (environmental), and ISO45001 (occupational health) certifications. Specific products can be certified to RoHS, REACH, or FDA standards upon request.
Can you develop steel balls for new applications?
Absolutely. Our R&D team has extensive experience in material science and surface engineering. We welcome collaboration on new product development projects, offering comprehensive support from material selection to prototype testing.
What is the shelf life of your steel balls?
Under proper storage conditions (dry environment, 20-25°C temperature), our steel balls maintain their properties for at least 5 years. For stainless steel balls, the shelf life extends to 10 years when stored in original sealed packaging.
Do you provide technical support for product selection?
Yes, our technical team offers free consultation to help clients select the most suitable steel ball grade based on their application requirements, including load capacity, rotational speed, environmental conditions, and cost considerations.
