Product Range: Full-Category Precision Steel Ball Solutions
Feige Steel Ball specializes in manufacturing two primary product categories: bearing steel balls and stainless steel balls, with precision grades ranging from G3 to G2000 – the most comprehensive gradient available in the industry. The size spectrum covers diameters from 0.3mm (suitable for precision instruments) up to 100mm (for heavy machinery applications), meeting virtually all industrial requirements.
The company’s material expertise extends beyond standard carbon steel to include various stainless steel grades (304, 316, 420, 440C), high carbon chromium bearing steel (GCr15), and specialized alloy compositions. This material diversity enables customization for specific performance requirements such as:
- High-speed rotation applications requiring minimal friction
- Corrosive environments demanding chemical resistance
- High-temperature operations needing thermal stability
- Heavy-load applications requiring exceptional strength
- Food-grade applications requiring FDA compliance
Customization Capabilities: Beyond Standard Solutions
Understanding that many industrial applications require specialized components, Feige Steel Ball offers comprehensive customization services that address four critical dimensions:
1. Material Composition: The company’s material engineers work with customers to develop optimal alloy formulations for specific operating conditions, balancing factors like hardness, corrosion resistance, and cost-effectiveness.
2. Surface Treatments: A variety of surface enhancement processes are available including polishing (to mirror finishes), grinding (for precise dimensional control), passivation (for stainless steel corrosion resistance), and specialized coatings (for wear reduction or chemical protection).
3. Dimensional Tolerances: For applications requiring extreme precision, the company can achieve tolerances as tight as ±0.001mm through advanced grinding and lapping processes, ensuring perfect fit in high-performance assemblies.
4. Geometric Configurations: Beyond standard spherical shapes, Feige Steel Ball produces custom geometries including truncated spheres, conical shapes, and specialized profiles for unique mechanical functions.
These customization capabilities are supported by an in-house R&D center equipped with advanced testing equipment including metallurgical microscopes, hardness testers, roundness measurement systems, and surface roughness analyzers. This vertical integration ensures complete control over the entire production process from material selection to final inspection.
Manufacturing Excellence: Precision Engineering at Scale
Feige Steel Ball’s production process combines traditional craftsmanship with modern automation to achieve both precision and efficiency. The manufacturing workflow includes:
| Production Stage | Key Processes | Quality Control |
|---|---|---|
| Raw Material Preparation | Wire drawing, cold heading, pre-forming | Chemical composition analysis, dimensional inspection |
| Rough Grinding | Multi-stage grinding process | Roundness measurement, surface defect inspection |
| Heat Treatment | Martensitic hardening, tempering | Hardness testing (HRC scale), microstructure analysis |
| Precision Grinding | Lapping and polishing to final dimensions | Dimensional tolerance verification (±0.001mm capability) |
| Surface Treatment | Polishing, passivation, coating | Surface roughness measurement, corrosion resistance testing |
| Final Inspection | 100% visual inspection, random sampling testing | Batch traceability documentation, certificate of conformity |
This systematic approach ensures that every steel ball leaving the factory meets stringent quality standards. The company’s quality assurance system tracks each production batch through every stage, maintaining complete traceability from raw material to finished product. This documentation is particularly valuable for customers in regulated industries like automotive and aerospace who require detailed production records for their own quality systems.
