6208 (CN) Bearing Product Overview & Core Advantages
The 6208 single row deep groove ball bearing is a fundamental precision bearing designed for robust performance in a wide range of industrial applications. Engineered to primarily accommodate radial loads, its open design and high-quality construction ensure reliable operation. A key advantage is its high limiting speed of 8,300 rpm, making it suitable for demanding, high-velocity machinery. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers excellent value and consistent performance for general-purpose use where high precision is not the primary requirement.
6208 (CN) Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 62 | Series code indicating a medium-width, deep groove design. |
| 08 | Bore diameter code, corresponding to a 40 mm bore. |
| (No Suffix) | Indicates an open (unsealed) bearing with no lubrication pre-applied, allowing for custom lubrication strategies. |
6208 (CN) Bearing Structural Features & Performance Benefits
- Optimized Radial Load Capacity: The single row deep groove raceway and high-grade chrome steel construction provide a high dynamic load rating of 6542 lbf and a static load rating of 4002 lbf, ensuring durability under significant stress.
- High-Speed Capability: The combination of an open design, a pressed steel cage, and precision manufacturing contributes to the bearing's high limiting speed, making it an excellent choice for high-speed applications.
- Standard Precision & Clearance: Conforms to ABEC 1 | ISO P0 tolerance class with a C0 radial internal clearance, offering a reliable and cost-effective solution for most industrial applications without the need for ultra-high precision.
- Versatile Material Compatibility: All core components—rings, balls, and cage—are manufactured from chrome steel, providing a consistent coefficient of thermal expansion and high resistance to wear.
6208 (CN) Bearing Typical Application Areas
