6208N/C3 Bearing Product Overview & Core Advantages
The 6208N/C3 is a single row deep groove ball bearing engineered for exceptional performance in demanding industrial applications. This metric bearing is characterized by its open design and snap ring groove on the outer ring, facilitating secure axial location within a housing. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers reliable operation and high precision. A key feature is its C3 radial internal clearance, which makes it ideally suited for applications involving thermal expansion, heavy loads, or high-speed operation, ensuring consistent performance and extended service life.
6208N/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6208 | Basic bearing designation indicating a single row deep groove ball bearing with a 40mm bore and 80mm outside diameter. |
| N | Signifies a snap ring groove on the outer ring, which aids in axial location and simplifies housing design. |
| C3 | Indicates a greater radial internal clearance than the standard C0 group. This is crucial for applications with high temperatures or heavy loads to prevent pre-loading and ensure smooth operation. |
6208N/C3 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The single row deep groove raceway design is optimized to support significant radial loads (Dynamic: 6542 lbf, Static: 4002 lbf). The robust construction using chrome steel for all components ensures high rigidity and dimensional stability under load.
- Optimized for Demanding Conditions: The C3 clearance is a critical performance feature. It accommodates shaft and housing fits that result in clearance reduction, as well as differential thermal expansion between the bearing and its surrounding components, preventing seizure and maintaining performance.
- Simplified Assembly & Location: The inclusion of a snap ring groove (N) allows for secure axial positioning of the bearing within the housing, reducing the complexity and cost of the housing design and assembly process.
- Broad Operating Range: With a limiting speed of 8,300 rpm and a temperature range from -30°C to 120°C, this bearing is versatile for a wide array of industrial environments.
6208N/C3 Bearing Typical Application Areas
The 6208N/C3 is a versatile component found in numerous industrial sectors. Its combination of high load capacity, C3 clearance, and snap ring groove makes it an ideal choice for:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Fans and Blowers
- Material Handling Equipment (Conveyors, Pulleys)
- Agricultural Machinery
- General machinery requiring reliable radial bearing support with secure axial location.
