306SFF Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| SFF | Specific manufacturer designation for this bearing series, indicating its standard open construction and dimensional specifications. |
| Open (No Seal) | The bearing is supplied without seals or shields, allowing for higher limiting speeds and facilitating custom lubrication regimes as required by the application. |
| None (Lubrication) | The bearing is supplied without factory-applied grease, providing flexibility for the user to select the optimal lubricant for their specific operating conditions. |
306SFF Bearing Structural Features & Performance Benefits
- High Load Capacity: The single row deep groove raceway geometry is designed to support significant radial dynamic load ratings (6677 lbf) and radial static load ratings (4856 lbf), ensuring reliable performance under demanding conditions.
- Precision & Consistency: Manufactured to ABEC 1 tolerance standards with a CN radial internal clearance, this bearing offers precise running accuracy and low vibration for smooth operation.
- High-Speed Capability: The open design and chrome steel cage contribute to a high limiting speed of 11,000 rpm, making it suitable for applications requiring rapid rotation.
- Material Integrity: All core components—rings, balls, and cage—are constructed from chrome steel, providing excellent hardness, wear resistance, and a long operational lifespan.
306SFF Bearing Typical Application Areas
The 306SFF is ideally suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Generators
- Industrial Gearboxes
