Our bearings are manufactured using vacuum-degassed bearing steel sourced from Baosteel and Shougang, ensuring minimal non-metallic inclusions and extended fatigue life. Each production batch undergoes 100% dimensional inspection using CMM (Coordinate Measuring Machines) and noise testing with Anderol measurement systems.

Quality Control Process: From Raw Material to Final Packaging

Quality assurance is not a department at SDF Bearing Group; it is a culture embedded in every stage of production. We follow a rigorous 7-step quality control process that aligns with international standards including ISO 9001:2015, IATF 16949:2016, and the Chinese GB/T 307.1-2016 standard.

Step 1: Incoming Raw Material Inspection

Every batch of bearing steel is tested for chemical composition using a Spectro Maxx spectrometer. We reject any material that does not meet our strict specifications for carbon content, chromium percentage, and inclusion rating.

Step 2: Forging and Heat Treatment

Our forging process uses precision induction heating to achieve uniform grain structure. After forging, rings undergo spheroidizing annealing and quenching-tempering cycles in controlled atmosphere furnaces. Hardness is verified using Rockwell and Vickers testers.

Step 3: Turning and Grinding

CNC lathes and high-speed grinding machines achieve tolerances within 2 microns. We use Marposs gauging systems for real-time dimensional feedback during the grinding process.

Step 4: Cage and Rolling Element Assembly

Cages are made from pressed steel, brass, or polyamide depending on application requirements. Rolling elements are sorted by grade G10 or higher to ensure consistent internal clearance.

Step 5: Final Assembly and Lubrication

Our cleanroom assembly area maintains Class 100,000 cleanliness. Bearings are lubricated with measured amounts of Shell or Mobil grease, and seals are installed using automated presses.

Step 6: Performance Testing

Each bearing undergoes vibration testing on a BVT-1A analyzer, noise testing in an anechoic chamber, and runout measurement. We randomly select 5% of each batch for extended endurance testing on our custom test rigs.

Step 7: Packaging and Documentation

Bearings are individually wrapped in VCI (Vapor Corrosion Inhibitor) paper, packed in export-grade cartons, and sealed in wooden crates for ocean freight. Each shipment includes a Certificate of Conformance, Material Test Certificate, and inspection reports.

Certifications That Matter for Global Trade

When importing bearings from China, buyers need assurance that products meet their local regulatory requirements. Here are the key certifications our factory maintains:

  • ISO 9001:2015 - Quality management system for consistent product quality.
  • IATF 16949:2016 - Automotive industry standard, essential for OEM suppliers.
  • CE Marking - Compliance with European health, safety, and environmental standards.
  • RoHS Directive 2011/65/EU - Restriction of hazardous substances for European markets.
  • REACH Regulation (EC) No 1907/2006 - Registration, evaluation, authorization of chemicals.
  • GB/T 307.1-2016 - Chinese national standard for rolling bearings.
  • ABEC 1 / ABEC 3 / ABEC 5 - Precision grades recognized globally.

We also offer customized certification packages for specific markets. For example, shipments to Saudi Arabia require SASO certification, while exports to Indonesia need SNI marking. Our export documentation team ensures all paperwork is complete and compliant with local customs authorities.

HS Code Classification for Smooth Customs Clearance

Correct HS code classification is critical for avoiding customs delays and unexpected duties. For bearings exported from China, the primary HS code is 8482.10 (Ball bearings) and 8482.20 (Tapered roller bearings). However, specific sub-codes vary by product type:

  • 8482.10.10 - Deep groove ball bearings with outer diameter not exceeding 30 mm
  • 8482.10.90 - Other ball bearings
  • 8482.20.10 - Tapered roller bearings with outer diameter not exceeding 100 mm
  • 8482.20.90 - Other tapered roller bearings
  • 8482.30.00 - Spherical roller bearings
  • 8482.50.00 - Cylindrical roller bearings

We provide HS code recommendations with every quotation and ensure that commercial invoices and packing lists are correctly annotated to match the customs declaration. For shipments to the European Union, the TARIC code may require additional digits, and we assist in determining the correct subheading.
