6208-2RS1/C3 Bearing Product Overview & Core Advantages
The 6208-2RS1/C3 is a single row deep groove ball bearing engineered for high reliability in demanding applications. This metric bearing excels at handling primarily radial loads and offers robust performance due to its sealed construction. Its key advantages include a generous C3 radial internal clearance for thermal expansion management in applications with elevated operating temperatures, and integrated contact seals (2RS1) that effectively protect against contamination. The combination of chrome steel components and ABEC 1 (ISO P0) precision ensures consistent operation and long service life, making it a versatile and dependable choice for industrial machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6208 | Standard series designation for a single row deep groove ball bearing with a 40 mm bore and 80 mm outside diameter. |
| 2RS1 | Bearing is fitted with contact seals on both sides. The "RS1" type seal is made of NBR rubber and provides excellent protection against dust and moisture ingress. |
| /C3 | Indicates a radial internal clearance greater than the Normal (CN) group. This is crucial for applications where shaft and housing fits are tight or operational temperatures are high, preventing pre-load and ensuring smooth running. |
6208-2RS1/C3 Bearing Structural Features & Performance Benefits
- Sealed for Protection and Longevity: The 2RS1 rubber contact seals on both sides effectively shield the bearing's internals from contaminants like dust and splashing fluids. This design significantly extends the bearing's operational life and is ideal for applications where re-lubrication is difficult.
- Optimized Internal Clearance: The C3 clearance is a critical feature that accommodates thermal expansion of the shaft and housing. This prevents excessive pre-loading at operating temperature, which can lead to increased friction, heat generation, and premature failure.
- Robust Load Capacity: Manufactured from high-grade chrome steel, this bearing offers a substantial dynamic load rating of 6542 lbf and a static load rating of 4002 lbf. Its deep groove raceway and single-row design provide excellent performance under radial loads.
- Standard Precision for General Applications: With a tolerance class of ABEC 1 | ISO P0, this bearing delivers reliable and consistent performance for a wide range of industrial uses without the need for ultra-high precision.
