6307-2Z/C3GJN Bearing Product Overview & Core Advantages
The 6307-2Z/C3GJN is a single row deep groove ball bearing designed for robust performance in demanding applications. This shielded bearing excels at handling primarily radial loads and offers high operational reliability. Its key advantages include a generous C3 radial internal clearance for thermal expansion management, making it suitable for applications with significant temperature variations. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent performance and long service life, while the integral shields protect against contamination.
6307-2Z/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| -2Z | Non-contact steel shields on both sides | Provides effective protection against dust and solid contaminants while maintaining low friction and high-speed capability. |
| /C3 | Greater than normal radial internal clearance | Accommodates shaft expansion due to heat, preventing preload and potential bearing seizure in high-temperature operations. |
| GJN | Lightly pre-lubricated with a polyurea base grease | Offers a ready-to-install solution with good high-temperature stability and extended lubrication intervals. |
6307-2Z/C3GJN Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: The single row deep groove raceway and high-quality chrome steel construction (rings, balls, and cage) provide a high radial dynamic load rating of 7509 lbf and static load rating of 4339 lbf, ensuring durability under significant stress.
- Optimized Internal Clearance: The C3 clearance is a critical feature for applications prone to thermal expansion, ensuring stable operation and preventing binding across the specified temperature range of -30°C to 120°C.
- High-Speed Capability: With a limiting speed of 8,500 rpm, the combination of the deep groove geometry, steel cage, and non-contact shields allows for smooth, high-rotation operation.
- Low-Maintenance & Contamination Resistance: The integral 2Z shields and factory-applied GJN grease create a sealed, pre-lubricated unit that is protected from contaminants and is ready for long-term service with minimal maintenance.
6307-2Z/C3GJN Bearing Typical Application Areas
This versatile bearing is ideally suited for a wide range of industrial machinery, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring reliable, medium-duty radial support
