6208-2RS1/C4 Bearing Product Overview & Core Advantages
The 6208-2RS1/C4 is a single row deep groove ball bearing designed for robust performance in demanding applications. Its primary advantage lies in its ability to efficiently handle radial loads while also accommodating moderate axial loads in both directions. This bearing features integral contact seals (2RS1) for superior contamination protection and is supplied with a greater radial internal clearance (C4), making it exceptionally suitable for applications involving thermal expansion or where shaft fits may induce preload. Its compact design, high load capacity, and reliable sealed construction ensure long service life and minimal maintenance.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6208 | Basic bearing series and size designation (Deep Groove Ball Bearing, 40mm bore, 80mm OD). |
| 2RS1 | Bearing is equipped with two NBR contact seals on both sides. This provides excellent protection against contaminants and retains lubricant. |
| C4 | Indicates a greater radial internal clearance than the normal (C0) group. This is critical for applications with significant temperature gradients or interference fits. |
6208-2RS1/C4 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The single row deep groove raceway geometry and high-quality chrome steel construction provide a high radial dynamic load rating of 6542 lbf and a radial static load rating of 4002 lbf, ensuring stable operation under significant loads.
- Effective Sealing: The 2RS1 contact seals are highly effective at excluding moisture, dust, and other contaminants, while also retaining lubricant. This significantly extends the bearing's service interval and operational life in harsh environments.
- Optimized Internal Clearance: The C4 clearance is engineered for applications where thermal expansion of the shaft or housing is expected. It prevents operational issues caused by thermal preload, ensuring smooth running and preventing premature failure.
- Standard Precision & Material Quality: Manufactured to ABEC 1 | ISO P0 tolerance class with rings, balls, and cage made from high-grade chrome steel, this bearing guarantees consistent performance and durability.
6208-2RS1/C4 Bearing Typical Application Areas
- Electric Motors and Generators
- Industrial Gearboxes and Power Transmission Systems
- Agricultural Machinery (e.g., conveyors, rollers)
