6306-2RS1NR/C3HT51 Bearing Product Overview & Core Advantages
The 6306-2RS1NR/C3HT51 is a single row deep groove ball bearing engineered for high reliability in demanding applications. This sealed bearing features a snap ring groove on its outer ring for secure axial location within a housing. Its C3 radial internal clearance makes it suitable for applications with thermal expansion or where interference fits are used. Pre-lubricated with high-temperature grease (HT51), it offers long-term, maintenance-free operation across a wide temperature range, delivering robust performance for radial loads and moderate axial loads.
6306-2RS1NR/C3HT51 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| -2RS1 | Contact seals on both sides | Provides excellent protection against contaminants and retains lubricant effectively. |
| NR | Snap ring groove on the outer ring | Simplifies axial location and bearing mounting within the housing, reducing assembly complexity. |
| /C3 | Greater than normal radial internal clearance | Accommodates thermal expansion and interference fits, preventing operational issues from preload. |
| HT51 | High-temperature grease | Enables reliable performance within the specified temperature range of -30°C to 120°C. |
6306-2RS1NR/C3HT51 Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured from chrome steel for both rings and balls, this bearing ensures high durability and resistance to wear under the specified radial dynamic load rating of 6002 lbf.
- Effective Sealing: The double-sided contact seals (2RS1) provide a superior barrier against dust, moisture, and other contaminants, significantly extending bearing service life in harsh environments.
- Simplified Mounting: The integrated snap ring groove (NR) allows for straightforward axial fixation, saving space and simplifying the overall housing design.
- Optimized Internal Clearance: The C3 clearance is ideal for applications where shaft or housing fits, or operational temperatures, could otherwise lead to detrimental bearing preload.
- Maintenance-Free Operation: Pre-lubricated with high-temperature grease, the bearing is ready for immediate use and requires no relubrication, reducing lifecycle costs.
6306-2RS1NR/C3HT51 Bearing Typical Application Areas
This versatile deep groove ball bearing is ideally suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Fans
- Material Handling Conveyors
- Agricultural Machinery
- Automotive Components (e.g., alternators, idlers)
