Overview & Engineering Structure
Deep Groove Ball Bearings are the most widely used roller bearing type in the world, characterized by their uninterrupted, deep raceway grooves. These grooves have a close osculation with the balls, enabling the bearings to accommodate radial loads and moderate axial loads in both directions. Backed by over 15 years of manufacturing expertise, Welink Bearing produces these components with optimized internal geometry to ensure low friction, minimal noise, and reliable high-speed rotation.
Nomenclature & Series Breakdown
In international bearing standards, standard metric deep groove ball bearings primarily use the prefix "6". The subsequent digits indicate the dimensional series (width and outer diameter) and bore size. Our comprehensive catalog covers:
• The 6000 Family: Including 60, 62, 63, and 64 series, ranging from light-duty space-saving models to extra-heavy-duty configurations.
• Thin-Section Series: The 67, 68, and 69 series, engineered for compact, weight-critical applications.
• Specialty Series: Including MR (Micro/Miniature), R (Imperial/Inch standard), and MF (Miniature Flanged) series for highly specific mounting requirements.
Key Technical Capabilities
• Precision & Clearance: Available in strict ISO 492 P0 to P5 precision grades, with internal clearances (such as standard CN, C3, and motor-specific CM) tailored to manage thermal expansion.
• Sealing Options: Offered in Open, ZZ (metal shields), and 2RS/2RZ (rubber seals) variations to protect against industrial contaminants and retain high-quality lubrication.
Primary Application Industries
Due to their versatility and low-maintenance design, these bearings are the foundation of modern machinery. They are heavily utilized in electric motors, smart home appliances, motorcycle components, robotics, and general industrial gearboxes.
