6209-2RS2/C3WT Bearing Product Overview & Core Advantages
The 6209-2RS2/C3WT is a single row deep groove ball bearing designed for robust performance in demanding applications. As a metric bearing, it excels in handling significant radial loads while also accommodating moderate axial loads in both directions. Its key advantages stem from its sealed construction and C3 radial internal clearance, making it an ideal choice for applications requiring high reliability, extended service life, and minimal maintenance. The combination of chrome steel components and precision ABEC 1 | ISO P0 tolerances ensures consistent operation and durability.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6209 | Standard designation for a single row deep groove ball bearing with a 45mm bore and 85mm outside diameter. |
| 2RS2 | Indicates the bearing is fitted with two high-performance synthetic rubber seals (one on each side) for superior protection against contaminants and moisture retention. |
| C3 | Specifies a greater radial internal clearance than the standard C0 group. This is beneficial for applications with thermal expansion, such as in electric motors, or where interference fits are used. |
| WT | This suffix signifies that the bearing is supplied without factory-fill lubrication (None). This allows the user to apply a specific lubricant suited to their unique operational requirements. |
6209-2RS2/C3WT Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The 2RS2 rubber contact seals provide excellent defense against dirt, dust, and moisture ingress, significantly extending bearing life in contaminated environments. This contributes to a maintenance-free or low-maintenance operational profile.
- Optimized Internal Clearance: The C3 radial clearance ensures stable operation under conditions that generate heat, preventing thermal preload and potential seizure. This makes the bearing suitable for applications with high rotational speeds or significant temperature gradients.
- High Load Capacity: 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, ensuring reliable performance under substantial radial loads.
- Precision and Speed: Built to ABEC 1 | ISO P0 tolerance standards, the bearing provides smooth and quiet running. It achieves a limiting speed of 7,700 rpm, making it a capable high-speed bearing for its size class.
- Application-Specific Lubrication: The WT (without grease) feature offers flexibility, allowing engineers to select a specialized lubricant that perfectly matches the temperature range (from -30°C to 120°C) and environmental conditions of their specific application.
6209-2RS2/C3WT Bearing Typical Application Areas
The 6209-2RS2/C3WT is widely used across various industries due to its versatile and robust design. Key application areas include:
- Electric Motors and Generators: Ideal for main shafts where C3 clearance accommodates thermal expansion.
- Industrial Gearboxes and Transmissions: Provides reliable support for shafts under heavy radial loads.
- Material Handling Equipment: Conveyor rollers, pulleys, and fans benefit from its sealed and durable construction.
- Agricultural Machinery: Withstands harsh, dusty environments in equipment like pumps and augers.
- General Industrial Machinery: A go-to choice for pumps, compressors, and blowers requiring a standard-sized, high-performance ball bearing.
