6309-2RS1/C3GJN Bearing Product Overview & Core Advantages
The 6309-2RS1/C3GJN is a sealed single row deep groove ball bearing designed for robust performance in demanding applications. This metric bearing features a C3 radial internal clearance and integrated rubber seals (2RS1) for enhanced contamination protection. Its construction enables efficient handling of radial loads while accommodating moderate axial loads in both directions. Manufactured to ABEC 1/ISO P0 tolerance standards with chrome steel components, it delivers reliable operation and extended service life across diverse industrial environments.
6309-2RS1/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Impact |
|---|---|---|
| 6309 | Basic designation: 45mm bore, 100mm OD, 25mm width | Standard dimensions for medium-duty applications |
| 2RS1 | Double rubber contact seals on both sides | Superior protection against contaminants and moisture |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-temperature operations |
| GJN | Grease filling with polyurea thickener | Extended lubrication intervals and stable performance |
6309-2RS1/C3GJN Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway design ensures smooth operation and efficient load distribution, making it suitable for both radial and combined loading conditions.
Double Rubber Seals (2RS1): Provide excellent sealing effectiveness against dust, dirt, and moisture ingress, significantly extending bearing service life in contaminated environments.
C3 Internal Clearance: This expanded radial clearance accommodates shaft and housing fits that may cause preload, as well as thermal expansion in applications with elevated operating temperatures.
Chrome Steel Construction: All components including rings, balls, and cage are manufactured from high-grade chrome steel, ensuring high durability and consistent performance under dynamic loads up to 11,915 lbf.
Pre-lubricated Design: Factory-filled with GJN polyurea grease enables maintenance-free operation throughout the bearing's service life in most applications.
