6209/C3W64 Bearing Product Overview & Core Advantages
The 6209/C3W64 is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This metric bearing is characterized by its ability to accommodate high radial loads and moderate axial loads in both directions. Its open design facilitates efficient heat dissipation, while the Solid Oil lubrication ensures long-term, maintenance-free operation across a wide temperature range. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers reliable precision and is an excellent choice for applications requiring consistent performance under varied load conditions.
6209/C3W64 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Benefit |
|---|---|---|
| 6209 | Standard designation for a single row deep groove ball bearing with a 45mm bore and 85mm OD. | Defines the core bearing dimensions and type. |
| /C3 | Specifies a greater radial internal clearance than normal. | Ideal for applications with significant thermal expansion or where interference fits are used. |
| W64 | Indicates the bearing is pre-lubricated with Solid Oil. | Provides a sealed-for-life lubrication system, offering protection in contaminated environments and eliminating relubrication needs. |
6209/C3W64 Bearing Structural Features & Performance Benefits
- High Load Capacity: The optimized raceway geometry and use of high-grade chrome steel for all components (rings, balls, cage) provide a high dynamic load rating of 7351 lbf and a static load rating of 4564 lbf, ensuring durability under substantial radial loads.
- Solid Oil Lubrication System: The W64 suffix denotes a polymer matrix saturated with oil, which acts as a built-in reservoir. This design prevents oil leakage, resists wash-out, and maintains effective lubrication from -30°C to 120°C, significantly extending service life in harsh conditions.
- Optimized Internal Clearance: The C3 clearance is engineered for applications where thermal expansion or shaft/housing fits could reduce operational clearance to zero, preventing premature bearing failure due to overheating and seizure.
- Precision Engineering: Manufactured to ABEC 1 (ISO P0) tolerance class, this bearing ensures smooth, low-vibration operation, contributing to the overall efficiency and reliability of the machinery.
6209/C3W64 Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Fans and Blowers
- Material Handling Conveyors
