6306-2RS1/C3GJN Bearing Product Overview & Core Advantages
The 6306-2RS1/C3GJN is a sealed deep groove ball bearing designed for reliable performance in demanding applications. This single row bearing excels at handling radial loads while also accommodating moderate axial loads in both directions. Its key advantages include extended service life due to its integral contact seals and a C3 radial internal clearance, which makes it particularly suitable for applications involving thermal expansion or where interference fits are used. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers a robust balance of precision and durability for general industrial use.
6306-2RS1/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance & Benefit |
|---|---|---|
| 6306 | Basic series number (30mm bore, 72mm OD) | Defines the standard bearing dimensions. |
| 2RS1 | Contact seals on both sides | Provides effective protection against contaminants and retains lubricant, enhancing reliability. |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion and interference fits, preventing operational issues. |
| GJN | Grease type designation | Specifies the high-quality, pre-applied lubricant suitable for the bearing's temperature range. |
6306-2RS1/C3GJN Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured entirely from chrome steel for rings, balls, and cage, this bearing delivers high strength and durability. With a radial dynamic load rating of 6002 lbf and a static load rating of 3372 lbf, it is engineered to handle significant radial loads in continuous operation.
- Enhanced Sealing & Contamination Resistance: The integral 2RS1 contact seals on both sides effectively shield the internal components from dust, moisture, and other contaminants. This design also retains the factory-applied grease, contributing to a long, maintenance-free service life in challenging environments.
- Optimized Internal Clearance for Stable Operation: The C3 radial internal clearance is a critical feature that prevents excessive preload and potential overheating in applications subject to shaft and housing fits or significant temperature variations, ensuring stable performance.
- Balanced High-Speed Capability: With a limiting speed of 9,600 rpm, this bearing is capable of operating efficiently in a wide range of high-speed machinery, supported by its precision construction and effective sealing.
