6309-2RS1/C3LT20 Bearing Product Overview & Core Advantages
The 6309-2RS1/C3 is a sealed deep groove ball bearing designed for reliable performance in demanding industrial applications. As a single row bearing, it excels at handling high radial loads while also accommodating moderate axial loads in both directions. Its key advantages include robust construction, extended service life due to integrated seals, and a generous C3 radial internal clearance suitable for applications with thermal expansion or heavy interference fits. This bearing is engineered for high reliability and consistent operation.
6309-2RS1/C3LT20 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6309 | Basic bearing series, indicating a medium width series with a 45mm bore. |
| 2RS1 | Bearing is equipped with two contact seals (RS1 type) on both sides, providing excellent protection against contaminants and retaining lubricant. |
| C3 | Specifies a radial internal clearance greater than the Normal (CN) group. This is optimal for applications with expected thermal expansion or heavy press fits. |
6309-2RS1/C3LT20 Bearing Structural Features & Performance Benefits
- Robust Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing delivers a high dynamic load rating of 11,915 lbf and a static load rating of 7,194 lbf, ensuring durability under significant radial stresses.
- Enhanced Sealing & Protection: The two contact seals (2RS1) effectively shield the internal components from dust, moisture, and other contaminants, while also retaining lubricant for long-term, maintenance-free operation.
- Optimized Internal Clearance: The C3 clearance provides operational stability in applications prone to shaft expansion due to heat or where tight interference fits are used, preventing premature failure from excessive preload.
- Precision & Consistency: Manufactured to ABEC 1 | ISO P0 tolerance standards, ensuring reliable dimensional accuracy and smooth running for general industrial use.
6309-2RS1/C3LT20 Bearing Typical Application Areas
This versatile bearing is commonly specified in a wide range of industrial machinery, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Conveyors
- Agricultural Machinery
- General Industrial Machinery requiring reliable, sealed bearing solutions.
