Product Range: Full-Category Solutions for Industrial Needs
Feige’s core product portfolio comprises two main categories: bearing steel balls and stainless steel balls, both available in the industry’s most comprehensive specification range:
- Precision Grades: G3 to G2000 full gradient standards, covering ultra-high precision (G3-G10) for aerospace applications to standard precision (G100-G2000) for general industrial use
- Size Spectrum: 0.3mm micro balls for precision instruments to 100mm large balls for heavy machinery, with intermediate sizes available in 0.1mm increments
- Material Options: High-carbon chromium bearing steel (GCr15), stainless steel (304/316/440C), carbon steel, brass, and other specialty alloys
- Surface Treatments: Polishing, grinding, passivation, blackening, electroplating, and custom coatings for specific environmental requirements
Customization Capabilities: Beyond Standard Solutions
Understanding that standard products cannot meet all industrial requirements, Feige has invested heavily in custom manufacturing capabilities. Our non-standard production services include:
- Material Engineering: Custom alloy formulations for specific mechanical properties or environmental resistance
- Dimensional Tolerance: Precision control beyond standard grades, with Cpk values ≥1.33 for critical dimensions
- Geometric Shapes: Spherical, cylindrical, conical, and other specialty shapes for unique applications
- Surface Modifications:
Custom textures, grooves, holes, or other features for functional requirements
This customization capability has enabled us to serve niche markets such as medical implants (requiring biocompatible materials and ultra-clean processing), semiconductor manufacturing (requiring vacuum-compatible materials and nanometer-level precision), and deep-sea exploration equipment (requiring corrosion resistance under extreme pressure).
Quality Control: From Raw Material to Final Inspection
Feige’s quality management system integrates advanced testing equipment with rigorous procedural controls. Key quality assurance measures include:
| Inspection Stage | Testing Equipment | Control Parameters |
|---|---|---|
| Raw Material | Spectral analyzer, metallographic microscope | Chemical composition, grain size, non-metallic inclusions |
| Cold Heading | Digital projection仪, roundness tester | Dimensional accuracy, surface defects |
| Heat Treatment | Hardness tester, metallographic microscope | Case depth, surface hardness, core hardness |
| Final Grinding | Roundness/cylindricity tester, surface roughness仪 | Geometric tolerance, surface finish |
| Cleaning | Particle counter, cleanliness tester | Residual contaminants, cleanliness class |
Our laboratory maintains calibration records for all testing equipment traceable to national standards, with regular inter-laboratory comparisons to ensure measurement accuracy. For critical applications, we provide material certificates (3.1B or 3.1C per EN 10204) and full inspection reports with each shipment.
Export Services: Streamlining International Procurement
Recognizing the complexities of global supply chains, Feige has developed a comprehensive export service system to support international clients:
- Documentation: Full set of export compliance documents including certificate of origin, quality certificates, packing lists, and commercial invoices

- Logistics: Coordination with major freight forwarders for optimal shipping routes, with experience in handling dangerous goods and temperature-sensitive cargo
- Customs: Assistance with HS code classification, duty optimization, and import regulation compliance for target markets
This service model has proven particularly valuable during global supply chain disruptions. In 2021, when maritime shipping faced unprecedented delays, our logistics team rerouted multiple shipments through air freight and rail-sea intermodal solutions, ensuring on-time delivery for critical orders to European automotive manufacturers.
After-Sales Support: Building Long-Term Partnerships
Feige’s commitment to client success extends beyond product delivery. Our after-sales service system includes:
- 24/7 Technical Support: Multilingual engineering team available via phone, email, or video conference for troubleshooting
- Quality Warranty: Free replacement for any product failing to meet specified parameters within 12 months of delivery
- Process Improvement: Regular follow-up visits to understand application performance and suggest optimization opportunities
- Training Programs: On-site or virtual training on product selection, handling, and maintenance for client personnel
In one notable case, a Middle Eastern construction equipment manufacturer experienced premature bearing failure due to improper steel ball selection. Our application engineers conducted a site visit, analyzed the operating conditions, and recommended a switch to our specially coated stainless steel balls. This solution extended bearing life by 300%, leading to a multi-year supply contract.
FAQ
What precision grades of steel balls does Feige offer?
We produce steel balls in full precision gradient from G3 to G2000. G3-G10 grades meet aerospace and medical standards with roundness ≤0.1μm, while G100-G2000 grades serve general industrial applications with cost-effective precision. Our quality system ensures each batch maintains consistent tolerance within the specified grade.
Can you manufacture steel balls smaller than 0.3mm or larger than 100mm?
While 0.3mm-100mm represents our standard production range, we regularly produce balls outside this spectrum for special projects. The smallest we’ve manufactured was 0.1mm for semiconductor applications using specialized cold heading equipment, and the largest was 300mm for decorative architectural features using forging and machining processes.
How do you ensure surface cleanliness for food-grade stainless steel balls?
For food contact applications, we implement multiple cleaning stages: ultrasonic degreasing, alkaline cleaning, acid passivation, pure water rinsing, and vacuum drying. The final cleanliness level reaches Class III per ISO 4406 (≤25/22/19 particles), with optional electropolishing for enhanced corrosion resistance and reduced bacterial adhesion.
What is your minimum order quantity for custom steel balls?
Our MOQ depends on the complexity of customization. For simple dimension changes within existing tooling, we can accept orders as low as 10,000 pieces. For completely new tooling (special shapes/materials), the MOQ typically starts at 50,000 pieces to amortize the setup costs. We offer sample production (50-500 pieces) for qualification testing at additional cost.
How do you handle confidentiality for custom designs?
We recognize the importance of intellectual property protection in custom manufacturing. All client drawings, specifications, and technical data are stored in our secure ERP system with access restricted to authorized personnel. We sign non-disclosure agreements (NDAs) before project kickoff and maintain confidentiality throughout the partnership lifecycle.
