As a global leader in precision bearing steel production, Changzhou Feige Steel Ball Co., Ltd. has established itself as the premier Indonesia high carbon chrome bearing steel manufacturer through decades of technical innovation and quality commitment. Our state-of-the-art production facilities spanning 18,000㎡ in Changzhou, China, enable us to produce 4,000 tons annually of premium bearing steel balls that meet the most demanding industrial standards worldwide.
Technical Excellence in Bearing Steel Production
Our manufacturing process for high carbon chrome bearing steel incorporates advanced metallurgical techniques that ensure consistent material properties across all production batches. The chemical composition typically includes 1.0-1.5% carbon, 1.3-1.65% chromium, and controlled amounts of manganese, silicon, and molybdenum to achieve optimal hardness (60-67 HRC) and wear resistance. This precise formulation makes our bearing steel balls ideal for applications requiring high load capacity and long service life.
The production workflow begins with carefully selected raw materials that undergo stringent quality checks before entering the melting process. Our induction furnaces maintain precise temperature control during melting, followed by atomization to create uniform spherical particles. These particles then undergo cold heading, rough grinding, heat treatment, and final precision grinding to achieve the required dimensional accuracy and surface finish.
Comprehensive Product Range for Diverse Applications
As Indonesia’s trusted high carbon chrome bearing steel supplier, we offer a complete range of products covering diameters from 0.3mm to 100mm with precision grades from G3 to G2000. This extensive portfolio enables us to serve multiple industries including:
- Automotive components (transmission systems, wheel bearings)
- Industrial machinery (gearboxes, pumps, compressors)
- Aerospace applications (high-speed rotating components)
- Medical devices (precision surgical instruments)
- Consumer electronics (miniature motors, hard drives)
Our engineering team works closely with clients to develop customized solutions for specialized applications. This includes adjusting material composition for specific corrosion resistance requirements, creating non-standard shapes for unique mechanical designs, and implementing special surface treatments to enhance lubrication retention or reduce friction coefficients.
Quality Assurance System
Our commitment to quality is demonstrated through our quadruple international certifications: ISO9001 for quality management, IATF16949 for automotive industry standards, ISO14001 for environmental management, and ISO45001 for occupational health and safety. Each production batch undergoes rigorous testing including:
| Test Parameter | Testing Method | Acceptance Criteria |
|---|---|---|
| Dimensional Accuracy | Laser scanning, CMM measurement | ±0.001mm for G3 grade |
| Surface Roughness | Profilometer measurement | Ra ≤ 0.01μm |
| Hardness | Rockwell hardness tester | 60-67 HRC |
| Material Composition | Spectrochemical analysis | Meets AISI 52100 standard |

FAQ
What is the minimum order quantity for custom bearing steel balls?
Our minimum order quantity starts from 50,000 pieces for standard sizes and grades. For customized specifications, the MOQ depends on the complexity of the design but typically ranges from 10,000 to 50,000 pieces. We recommend discussing your specific requirements with our sales team for accurate quotation.
How do you ensure product consistency across large production batches?
We implement strict quality control measures at every production stage. This includes real-time monitoring of melting parameters, automated sorting systems for dimensional inspection, and statistical process control (SPC) for critical dimensions. Each production batch is assigned a unique traceability code that allows complete tracking of raw materials, production parameters, and quality test results.
What is your standard lead time for production and delivery?
For standard products from our inventory, we can ship within 7-10 working days after order confirmation. For custom orders, the production lead time is typically 4-6 weeks depending on order quantity and specification complexity. Shipping time varies by destination but averages 3-5 weeks for sea freight and 3-7 days for air freight.
Can you provide material certification for exported products?
Yes, we provide complete material certification documents with every shipment including mill test certificates, chemical composition analysis reports, and hardness test results. For clients requiring additional certification, we can arrange third-party inspection by SGS, BV, or other accredited inspection agencies at client’s expense.
