6309-2RS1NR/C3 Bearing Product Overview & Core Advantages
The 6309-2RS1NR/C3 is a sealed deep groove ball bearing designed for robust performance in demanding industrial applications. This single row bearing excels at handling high radial loads while also accommodating moderate axial loads in both directions. Its key advantages include the integration of contact seals (2RS1) for superior contamination exclusion, a snap ring groove (NR) on the outer ring for simplified axial location, and an optimized C3 radial internal clearance for stable operation under thermal expansion or heavy load conditions. This configuration makes it an ideal, maintenance-free solution for applications requiring high reliability and long service life.
6309-2RS1NR/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6309 | Basic designation: Metric deep groove ball bearing with 45mm bore, 100mm OD, 25mm width. | Defines standard bearing dimensions for interchangeability. |
| 2RS1 | Two contact seals (RS1 type) made of NBR rubber, one on each side. | Provides excellent protection against contaminants and retains lubricant, enabling a maintenance-free design. |
| NR | Snap ring groove on the outer ring. | Facilitates easy axial location within a housing, simplifying assembly and reducing component count. |
| C3 | Radial internal clearance greater than Normal (C0) group. | Accommodates thermal expansion and interference fits, preventing preload and ensuring smooth operation under heavy loads or elevated temperatures. |
6309-2RS1NR/C3 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for both rings, balls, and cage, this bearing offers high strength and durability. With a dynamic load rating of 11,915 lbf and a static load rating of 7,194 lbf, it is engineered to handle significant radial loads and ensure long-term operational reliability.
- Enhanced Sealing & Contamination Resistance: The 2RS1 contact seals effectively shield the internal components from dust, dirt, and moisture. This feature is critical for maintaining performance and extending service life in harsh environments, making the bearing effectively maintenance-free.
- Simplified Installation & Axial Location: The outer ring snap ring groove (NR) allows for secure axial positioning without the need for complex housing shoulders or end caps, streamlining the design and assembly process.
- Optimized Internal Clearance for Demanding Conditions: The C3 radial clearance provides operational stability in applications prone to thermal expansion or where heavy interference fits are used, preventing binding and reducing friction and heat generation.
6309-2RS1NR/C3 Bearing Typical Application Areas
The 6309-2RS1NR/C3 is widely used across various industries due to its sealed, robust, and easy-to-install design. Key application areas include:
- Electric Motors and Generators: For shaft support in industrial motors requiring sealed, long-life bearings.
- Material Handling Equipment: In conveyor pulleys, rollers, and gearboxes where contamination resistance is paramount.
- Agricultural Machinery: In tractors, combines, and other equipment operating in dusty and demanding conditions.
- Industrial Pumps and Fans: Providing reliable shaft support in units exposed to moisture or airborne particles.
- General Industrial Machinery: Any application requiring a standard-sized, sealed deep groove ball bearing with a snap ring for simplified mounting.
