In the highly specialized field of industrial components manufacturing, precision is not just a requirement – it’s the foundation of quality and performance. Changzhou Feige Steel Ball Co., Ltd. stands as a global leader in ultra precision steel ball production, combining cutting-edge technology with decades of expertise to deliver solutions that meet the most demanding industrial standards. As a state-level high-tech enterprise with 18,000㎡ of manufacturing space and 4,000 tons annual capacity, we’ve established ourselves as China’s premier full-category high-end steel ball export base.
The Core of Our Precision Manufacturing
Our ultra precision manufacturing system represents the culmination of years of technological investment and process optimization. The foundation lies in our state-of-the-art production facilities spanning 18,000 square meters across main and subsidiary plants. This expansive space houses specialized equipment for every stage of steel ball production – from raw material processing to final precision grinding.
The heart of our precision capabilities is our G3-G2000 grade production lines. These represent the highest standards in steel ball manufacturing, with G3 being the most precise grade available commercially. To achieve such extraordinary precision, we employ multi-stage grinding processes using diamond grinding wheels, combined with advanced lapping and polishing techniques that remove microscopic imperfections. Our quality control systems utilize laser measurement devices capable of detecting variations as small as 0.0001mm, ensuring every ball meets exacting specifications.
Our production team comprises over 100 skilled technicians and engineers, many with decades of experience in precision manufacturing. This human expertise, combined with our automated production lines, creates a perfect synergy where machine precision is guided by human insight. Continuous training programs keep our team updated with the latest manufacturing techniques and quality standards, maintaining our position at the forefront of precision technology.
Comprehensive Product Range for Diverse Applications
Changzhou Feige’s product portfolio addresses the complete spectrum of industrial needs through two primary material categories: bearing steel balls and stainless steel balls. Our bearing steel balls, manufactured from high-carbon chromium steel (GCr15), offer exceptional hardness (62-66 HRC) and wear resistance, making them ideal for high-load applications in automotive, aerospace, and heavy machinery.
The stainless steel ball range includes both 304 and 316 grades, providing excellent corrosion resistance for applications in chemical processing, food production, and marine environments. For specialized requirements, we offer other materials including carbon steel, brass, and ceramic balls, each processed through our ultra precision manufacturing system.
Precision Grades and Dimensional Range
Our precision steel balls cover the complete G3-G2000 grade spectrum, with each grade corresponding to specific surface roughness and roundness requirements. The G3 grade represents the pinnacle of precision, with surface roughness below 0.005μm and spherical deviation under 0.05μm. These ultra-high precision balls are essential for applications like gyroscopes, precision measuring instruments, and aerospace components.
In terms of dimensions, we produce steel balls from an incredibly small 0.3mm up to 100mm in diameter. This range enables us to serve both micro-precision applications like medical devices and watch components, as well as large industrial applications requiring heavy-duty balls for conveyor systems or mining equipment. Our ability to maintain consistent precision across this vast size range is a testament to our manufacturing expertise.
| Parameter | Specification |
|---|---|
| Diameter Range | 0.3mm – 100mm |
| Precision Grades | G3 to G2000 |
| Material Options | Bearing steel, stainless steel, carbon steel, brass, ceramic |
| Surface Finish | Ra 0.005μm to Ra 0.2μm |
| Hardness | 58-66 HRC (bearing steel) |
Custom Solutions for Specialized Requirements
While our standard product range meets most industrial needs, we recognize that many applications require bespoke solutions. Our custom manufacturing capabilities enable us to produce steel balls with specialized characteristics that go beyond standard specifications. This includes developing unique material compositions through precise alloying, creating non-spherical shapes like cylinders or cones, and implementing special surface treatments.
One of our most requested custom services is precision tolerance adjustment. While our standard production maintains extremely tight tolerances, some applications require even more precise dimensional control. We can manufacture balls with diameter tolerances as tight as ±0.001mm for applications where microscopic variations can impact performance. This capability is crucial for semiconductor manufacturing equipment, optical instruments, and high-precision bearings.
Surface modification is another area where our custom solutions excel. We offer various coating options including black oxide, nickel plating, and Teflon coating to enhance specific properties like corrosion resistance, lubricity, or electrical conductivity. For applications requiring extreme cleanliness, we provide ultra-clean processing that removes all contaminants and creates a sterile surface finish.
Non-Standard Shape Production
Our CNC machining centers enable us to produce steel components in virtually any shape required by our customers. This includes:
- Cylindrical rollers for needle bearings
- Conical components for specialized drives
- Asymmetrical shapes for unique mechanical systems
- Precision ground shafts and pins
Each non-standard shape undergoes the same rigorous quality control as our spherical products, ensuring dimensional accuracy and surface finish meet specifications.

FAQ
What makes your steel balls “ultra precision” compared to standard products?
Our ultra precision steel balls achieve grade G3-G5 specifications, which represent the highest precision category in the industry. This means surface roughness below 0.005μm and spherical deviation under 0.05μm, produced through multi-stage diamond grinding and polishing processes with laser-guided quality control at every stage.
Can you produce steel balls smaller than 1mm with consistent quality?
Absolutely. Our production capabilities include steel balls as small as 0.3mm in diameter with the same precision standards as our larger sizes. We use specialized equipment and processes to maintain dimensional accuracy and surface finish consistency even at these microscopic scales.
What certifications do your products carry for international markets?
We maintain four major international certifications: ISO 9001 (quality management), IATF 16949 (automotive industry quality), ISO 14001 (environmental management), and ISO 45001 (occupational health and safety). These certifications ensure our products meet global standards and our processes comply with international regulations.
How do you ensure quality consistency across large production batches?
Our quality control system incorporates several layers of inspection: incoming material verification, in-process monitoring using laser measurement devices, and final inspection with statistical sampling. For critical applications, we offer 100% inspection services using automated sorting machines that detect even microscopic defects.
