6209-2RS1TN9/GJN Bearing Product Overview & Core Advantages
The 6209-2RS1TN9/GJN is a single row deep groove ball bearing engineered for exceptional reliability in demanding applications. Its core advantage lies in its ability to efficiently handle radial loads while offering robust, sealed construction for long service life. This bearing is characterized by its compact design, high running accuracy conforming to ABEC 1 | ISO P0 tolerance class, and is pre-lubricated for immediate use, making it an ideal choice for applications requiring high reliability and minimal maintenance.
6209-2RS1TN9/GJN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance & Benefit |
|---|---|---|
| 2RS1 | Contact seals on both sides | Provides superior protection against contaminants and retains lubricant effectively, enhancing bearing life. |
| TN9 | Polyamide (Nylon) cage, glass fiber reinforced | Contributes to quiet operation, low friction, and is suitable for high-speed applications up to the limiting speed. |
| GJN | Pre-filled with a specific lithium soap complex grease | Ensures immediate lubrication upon installation, supports operation within the specified temperature range (-30° to 120 °C), and offers a maintenance-free solution. |
6209-2RS1TN9/GJN Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The 2RS1 contact seals on both sides effectively shield the internal components from dust, moisture, and other contaminants. This design significantly extends the bearing's operational lifespan, especially in harsh environments, and retains the lubricant, making it a maintenance-free component for its entire service life.
- Optimized Cage for High-Speed Operation: The TN9 glass fiber reinforced nylon cage is lightweight and possesses excellent sliding properties. This contributes to lower friction, reduced heat generation, and allows the bearing to achieve its high limiting speed of 7,700 rpm with stability and low noise.
- High Load Capacity and Precision: Manufactured from high-grade chrome steel for both rings and balls, this bearing offers a high dynamic load rating of 7351 lbf and a static load rating of 4564 lbf. Combined with the standard CN radial internal clearance and ABEC 1 precision, it ensures smooth running and reliable performance under radial loads.
- Ready-to-Use Lubrication: The bearing is pre-filled with GJN grease, which is suitable for the specified operating temperature range. This eliminates the need for initial lubrication, simplifies installation, and guarantees immediate, optimal performance.
6209-2RS1TN9/GJN Bearing Typical Application Areas
