311MFF Bearing Product Overview & Core Advantages
The 311MFF is a single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. Engineered with precision to ABEC 1 (ISO P0) standards, this bearing excels at handling primarily radial loads while offering reliable operation. Its open design allows for versatile lubrication options, and its construction from high-grade chrome steel ensures durability and a long service life, making it a robust choice for general machinery and equipment.
311MFF Bearing Model Code Explained, Specifications & Naming Convention
| Suffix / Prefix | Technical Meaning |
|---|---|
| 311 | Standard bore diameter series designation. |
| M | Machined brass cage, offering high strength and suitability for high-speed applications. |
| FF | Polyamide (plastic) window-type cage, glass fiber reinforced. Provides low friction and is suitable for high speeds. |
Note: The "M" and "FF" designations for the cage may be mutually exclusive in standard nomenclature. Please consult technical datasheets for the precise configuration of the 311MFF model.
311MFF Bearing Structural Features & Performance Benefits
- Robust Load Capacity: With a radial dynamic load rating of 17,805 lbf and a static load rating of 15,062 lbf, this bearing is built to handle significant radial forces in continuous operation.
- High-Speed Capability: The machined brass or reinforced polyamide cage contributes to stable operation at the limiting speed of 6,300 rpm, reducing friction and wear.
- Precision & Stability: Manufactured to ABEC 1 (ISO P0) tolerance class with a standard (CN) radial internal clearance, ensuring consistent performance, low noise, and minimal vibration.
- Versatile Application Range: The open seal type and wide operating temperature range (-30°C to 120°C) make it adaptable to various environments and lubrication regimes.
- Material Integrity: Constructed entirely from chrome steel for the rings, balls, and cage, providing excellent hardness, wear resistance, and dimensional stability.
