6309-2RS1NR (CN) Bearing Product Overview & Core Advantages
The 6309-2RS1NR (CN) is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This sealed bearing excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its key advantages include a snap ring groove on the outer ring for simplified axial location and secure mounting, combined with integrated contact seals for robust contamination protection. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent performance and is pre-lubricated for long-term, maintenance-free operation.
6309-2RS1NR (CN) Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Benefit |
|---|---|---|
| 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 secure mounting within a housing, reducing assembly complexity. |
| (CN) | Normal radial internal clearance (C0) | Standard clearance suitable for most common operating conditions and temperature ranges. |
6309-2RS1NR (CN) Bearing Structural Features & Performance Benefits
- Robust Sealing & Pre-Lubrication: The 2RS1 contact seals create an effective barrier against dust, moisture, and other contaminants, while the factory-applied grease ensures long-lasting, maintenance-free operation.
- Simplified Mounting & Axial Location: The snap ring groove (NR) on the outer ring allows for secure axial positioning within a housing, eliminating the need for complex housing shoulders and streamlining the assembly process.
- High Load Capacity & Durability: Constructed entirely from chrome steel for the rings, balls, and cage, this bearing offers a high dynamic load rating of 11,915 lbf and a static load rating of 7,194 lbf, ensuring reliable performance under significant radial loads.
- Precision & Consistency: Manufactured to ABEC 1 | ISO P0 tolerance class, the bearing provides consistent running accuracy and smooth operation, which is critical for reducing vibration and noise.
