In the competitive landscape of industrial components manufacturing, precision and reliability are paramount. Changzhou Feige Steel Ball Co., Ltd. stands as a beacon of excellence in producing high carbon chromium bearing steel products that meet the most stringent global standards. As a leading manufacturer with a sprawling 18,000 square meter production base and an impressive annual capacity of 4,000 tons, we have solidified our position among China’s top-tier steel ball producers.
Our Production Capabilities: A Class Apart
At Changzhou Feige, we don’t just manufacture steel balls – we engineer precision components that power industries worldwide. Our state-of-the-art facilities are equipped with advanced machinery and quality control systems that ensure every product meets exacting specifications. The high carbon chromium bearing steel we use provides exceptional hardness, wear resistance, and dimensional stability – crucial properties for demanding industrial applications.
Our production process begins with carefully selected raw materials that undergo rigorous testing before entering production. The high carbon chromium composition (typically 1.0-1.5% carbon and 1.3-1.65% chromium) gives our bearing steel balls their superior characteristics. Through precise heat treatment processes including quenching and tempering, we achieve the optimal balance of hardness and toughness that makes our products stand out in the market.

FAQ
What makes high carbon chromium bearing steel balls superior for industrial applications?
High carbon chromium bearing steel offers an optimal combination of hardness (typically 60-67 HRC after heat treatment), wear resistance, and fatigue strength. The chromium content (1.3-1.65%) provides excellent corrosion resistance while maintaining the steel’s ability to be hardened to high levels, making these balls ideal for demanding bearing applications where both durability and precision are required.
Can you produce steel balls with non-standard sizes or shapes?
Absolutely. As a custom steel ball manufacturer, we specialize in producing non-standard sizes, shapes, and material compositions. Our advanced manufacturing capabilities allow us to create balls as small as 0.3mm or as large as 100mm in diameter, with precision up to G3 grade for ultra-fine applications. We can also produce spherical, cylindrical, or custom-shaped components based on your specific requirements.
What quality control measures do you implement in production?
We maintain rigorous quality control throughout our production process: 1) Raw material inspection before production, 2) In-process inspection at every manufacturing stage, 3) Final inspection including dimensional checks, surface examination, and hardness testing, 4) Random sampling for destructive testing when required. Our facilities are ISO 9001 and IATF 16949 certified, ensuring systematic quality management at all levels.
How do you ensure environmental responsibility in your manufacturing?
Environmental stewardship is a core value at Changzhou Feige. We hold ISO 14001 certification for our environmental management system and continuously invest in cleaner production technologies. Our efforts include: 1) Efficient waste management and recycling programs, 2) Energy-saving equipment and processes, 3) Emission control systems, 4) Regular environmental impact assessments.
