208 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 208 | Standard metric series designation indicating bearing dimensions: 40mm bore, 80mm OD, 18mm width. |
| Open (No Seal Suffix) | No integral seals or shields, allowing for high-speed operation and custom lubrication regimes. |
| P0 (Tolerance Class) | Standard tolerance class per ISO standards, ensuring consistent dimensional accuracy for general applications. |
| CN (Radial Clearance) | Standard radial internal clearance for normal operating conditions and fits. |
208 Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The single row deep groove raceway geometry is engineered to support significant radial dynamic load rating of 7554 lbf, while also accommodating moderate axial loads in both directions.
- High-Speed Capability: Features a lightweight nylon cage that reduces centrifugal forces, contributing to a high limiting speed of 9,500 rpm. The open design minimizes friction and heat generation.
- Precision & Rigidity: Manufactured to P0 tolerance class with tight dimensional controls on the bore diameter, outside diameter, and width, ensuring precise fits and stable operation.
- Versatile Application Range: Constructed from through-hardened chrome steel for both rings and balls, providing excellent durability and a broad operating temperature range from -30°C to 120°C.
208 Bearing Typical Application Areas
This versatile 208 bearing is widely used across various industries due to its robust design and reliable performance. Common applications include:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Conveyors
- Agricultural Machinery
- General Industrial Machinery where high radial load capacity is required
