In modern industrial manufacturing, precision steel balls play a crucial role in ensuring equipment performance and reliability. As a professional bearing steel balls manufacturer with 18,000㎡ production facilities in Changzhou, China, Changzhou Feige Steel Ball Co., Ltd. has established itself as a global leader in precision steel ball production. With an annual capacity of 4,000 tons and comprehensive ISO certifications, our company delivers full-category steel ball solutions that meet the most demanding industrial requirements worldwide.
Comprehensive Product Range Covering All Precision Grades
Our core product portfolio includes two main categories: bearing steel balls and stainless steel balls, both manufactured to the highest international standards. The precision grades we offer span the complete G3-G2000 spectrum, ensuring we can meet requirements from ultra-high precision applications to general industrial uses. This comprehensive precision coverage makes us unique among steel ball manufacturers, as few competitors can provide such a wide range of accuracy levels from a single source.
The size range of our steel balls extends from 0.3mm micro balls suitable for precision instruments to 100mm large balls for heavy machinery applications. This versatility enables us to serve diverse industries including automotive, aerospace, medical devices, electronics, and general engineering. Our production capabilities cover both standard sizes and custom dimensions, with the flexibility to manufacture non-standard sizes according to specific customer requirements.
Advanced Manufacturing Capabilities for Custom Solutions
What truly distinguishes Changzhou Feige as a leading steel ball supplier is our advanced custom manufacturing capabilities. We understand that standard products often cannot meet the unique requirements of specialized applications. Therefore, we offer comprehensive customization services covering material composition, surface treatments, dimensional tolerances, and special shapes.
Our material options include various grades of bearing steel, stainless steel, carbon steel, and specialty alloys. Surface treatment capabilities range from standard polishing to specialized coatings like black oxide, nickel plating, and Teflon coating. For dimensional control, we can maintain tolerances as tight as ±0.001mm for ultra-precision applications. In terms of shapes, we produce not only standard spherical balls but also custom-designed forms like truncated balls, oval balls, and other special geometries required for specific mechanical functions.
Quality Assurance System Meeting International Standards
As a manufacturer holding ISO9001, IATF16949, ISO14001, and ISO45001 certifications, we implement a rigorous quality management system throughout our production processes. From raw material inspection to final product testing, every step follows standardized procedures to ensure consistent quality. Our in-house laboratory is equipped with advanced testing equipment including roundness measurement systems, surface roughness testers, and material analysis instruments.
The table below outlines our key quality control measures at different production stages:
| Production Stage | Quality Control Measures |
|---|---|
| Raw Material Inspection | Chemical composition analysis, hardness testing, inclusion rating |
| Cold Heading Process | Dimensional inspection, surface defect detection |
| Grinding Process | Roundness measurement, surface roughness testing |
