311SFFC Bearing Product Overview & Core Advantages
The 311SFFC is a single row deep groove ball bearing engineered for superior performance in demanding industrial applications. This precision bearing is characterized by its robust construction and adherence to ABEC 1 | ISO P0 tolerance standards, ensuring reliable operation and dimensional consistency. Its primary function is to efficiently support radial loads, making it an ideal component for systems requiring high rotational accuracy and durability. The open design facilitates versatile lubrication options, while the all-chrome steel construction provides excellent resistance to wear, contributing to a long service life and high operational reliability.
311SFFC Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 311 | Standard bore diameter code, indicating a 55mm bore. |
| SFF | Manufacturer-specific designation for filling slot construction. |
| C | Denotes a CN group radial internal clearance, which is the standard normal clearance for general applications. |
311SFFC Bearing Structural Features & Performance Benefits
- High Load Capacity: The single row deep groove raceway geometry is optimized to handle significant radial dynamic loads (17805 lbf) and radial static loads (15062 lbf), providing robust support for rotating shafts.
- Optimized for High-Speed Operation: With a limiting speed of 6,300 rpm, this bearing is suitable for high-velocity applications. The precision-ground components and stable cage contribute to smooth, low-vibration operation at high rotational speeds.
- Versatile Lubrication Compatibility: The open seal type allows for the application of a wide range of greases or oils, enabling users to select the optimal lubricant for specific temperature, speed, and environmental conditions.
- Durable Construction: Manufactured entirely from chrome steel for the rings, balls, and cage, this bearing offers high hardness, excellent resistance to fatigue, and reliable performance across a broad temperature range (-30°C to 120°C).
