6208 NR/C3W64 Bearing Product Overview & Core Advantages
The 6208 NR/C3W64 is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This metric bearing is distinguished by its snap ring groove on the outer ring, which facilitates secure axial location within a housing, and its Solid Oil lubrication for extended service life. Its C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used. Designed to primarily handle radial loads, it offers a high limiting speed and reliable operation, making it an excellent choice for applications requiring high reliability and simplified assembly.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6208 | Standard bore diameter 40 mm, outside diameter 80 mm, and width 18 mm. |
| NR | Outer ring features a snap ring groove. This allows for secure axial positioning, reducing housing design complexity and costs. |
| C3 | Greater than normal radial internal clearance. Ideal for applications with expected thermal expansion or heavy interference fits. |
| W64 | Designates Solid Oil lubrication. The bearing is filled with a polymer matrix saturated with oil, providing long-term, maintenance-free lubrication. |
6208 NR/C3W64 Bearing Structural Features & Performance Benefits
- Snap Ring Groove for Simplified Assembly: The integrated groove on the outer ring accommodates a snap ring, eliminating the need for complex end caps or housing shoulders. This design ensures secure axial location and simplifies housing design, leading to reduced manufacturing costs.
- Solid Oil Lubrication for Maintenance-Free Operation: The bearing is pre-lubricated with a solid, oil-saturated polymer. This technology offers superior performance compared to traditional greases, providing excellent contamination resistance, minimal leakage, and a long, reliable service life without re-lubrication.
- Optimized Internal Clearance for Stable Performance: The C3 radial clearance provides extra space between the rolling elements and raceways. This is critical for applications prone to thermal expansion or where press fits are used, preventing excessive preload and ensuring smooth, cool running.
- Robust Load Capacity and High-Speed Capability: Manufactured from chrome steel for both rings and balls, this bearing delivers a high dynamic load rating of 7306 lbf and a static load rating of 4271 lbf. Combined with a limiting speed of 11,000 rpm, it is built for durability and performance in demanding environments.
6208 NR/C3W64 Bearing Typical Application Areas
The 6208 NR/C3W64 is ideally suited for a wide range of industrial machinery where reliable, maintenance-free operation is paramount. Key application areas include:
- Electric Motors and Gearboxes: Used for shaft support, benefiting from the snap ring for easy location and Solid Oil for long life.
- Material Handling Equipment: Conveyor pulleys and rollers where contamination resistance is crucial.
- Agricultural Machinery: Implements and drives operating in harsh, dusty environments.
- Industrial Fans and Blowers: High-speed applications requiring stable performance and minimal maintenance.
- Pumps and Compressors: General industrial applications where the C3 clearance accommodates thermal changes.
