In the global industrial supply chain, precision steel balls serve as critical components in bearings, automotive parts, aerospace equipment, and medical devices. As a professional manufacturer with 18,000㎡ production facilities and 4,000 tons annual output, Changzhou Feige Steel Ball Co., Ltd. has established itself as China’s premier export base for high-precision steel balls. Our “Saige” brand products meet stringent international standards while offering unmatched customization capabilities for diverse industrial applications.
Comprehensive Product Range Covering All Precision Grades
Our core product portfolio includes two major categories: bearing steel balls and stainless steel balls, both manufactured to meet international quality standards. The precision grades span the complete G3-G2000 spectrum, enabling us to serve applications requiring:
- Ultra-high precision (G3-G10): Critical for aerospace bearings, medical implants, and semiconductor manufacturing equipment where micron-level accuracy is mandatory
- General precision (G16-G100): Standard requirements for automotive bearings, industrial machinery, and electrical appliances
- Heavy-duty precision (G200-G2000):
Designed for mining equipment, construction machinery, and other applications requiring exceptional durability under extreme loads
The dimensional range from 0.3mm to 100mm covers both micro-precision components and large industrial balls, with complete traceability through our ISO 9001-certified quality management system. Each production batch undergoes rigorous testing including roundness measurement, surface finish inspection, and material composition analysis to ensure 100% compliance with specifications.
Advanced Manufacturing Capabilities
Our production facilities feature state-of-the-art equipment from Germany and Japan, including:
- CNC cold heading machines for precise initial forming
- Multi-stage grinding lines with automatic size control
- Lapping machines achieving surface finishes below Ra 0.01μm
- In-house metallurgical laboratory for material verification
- Automated cleaning and packaging systems meeting food-grade standards
The dual-factory layout (main plant: 12,000㎡; branch plant: 6,000㎡) enables specialized production lines for different material types and precision grades. Our vertical integration from raw material procurement to finished product packaging ensures complete quality control throughout the manufacturing process.

The dedicated after-sales team provides 24/7 technical support and handles any quality concerns through our lifetime process tracking system.
FAQ
What precision grades can your steel balls achieve?
Our production covers the complete G3-G2000 precision spectrum. The achievable grade depends on material type and ball size – for example, we regularly produce G3-G10 grade stainless steel balls below 10mm diameter for medical applications, while G200-G1000 grade carbon steel balls above 50mm are common for mining equipment.
How do you ensure quality consistency for large orders?
We implement several quality control measures for bulk production: 1) Statistical process control (SPC) monitors key parameters in real-time during manufacturing 2) Automatic sorting machines classify finished products by size and roundness 3) Each batch includes sample testing against specification limits 4) Production records are stored for 10 years enabling full traceability.
What is your minimum order quantity for custom products?
The MOQ varies based on customization complexity. For simple size variations of standard products, we can accept orders from 5,000 pieces. For fully custom shapes or material compositions, the MOQ typically starts at 20,000 pieces to justify tooling and process setup costs. We offer sample production for qualification purposes before full-scale manufacturing.
How do you handle urgent delivery requests?
Our production system maintains 15% spare capacity specifically for emergency orders. For standard products, we can ship within 7 days from confirmed order for quantities up to 500,000 pieces. For custom products, our engineering team evaluates the feasibility of expedited production based on current factory load and provides realistic delivery timelines within 24 hours of inquiry.
What surface treatments do you recommend for corrosive environments?
For marine or chemical exposure applications, we offer three proven solutions: 1) 316 stainless steel with electropolishing (best corrosion resistance) 2) Carbon steel with triple-layer nickel-chrome plating (cost-effective alternative) 3) Specialized coatings like PTFE or ceramic deposits (for additional wear resistance). Our material engineers can recommend the optimal solution based on specific environmental parameters.
