306MFF Bearing Product Overview & Core Advantages
The 306MFF is a single row deep groove ball bearing designed for high-performance radial load applications. Engineered with precision tolerances (ABEC 1 | ISO P0) and manufactured from high-grade chrome steel, this bearing delivers reliable operation and long service life. Its open design allows for versatile lubrication options, making it suitable for a wide range of industrial machinery requiring robust and efficient rotational support.
306MFF Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| M | Brass Cage |
| FF | Polyamide (Nylon) Cage, Snap-Type on Both Sides |
Note: The absence of a seal suffix indicates an open bearing, providing maximum flexibility for custom lubrication systems.
306MFF Bearing Structural Features & Performance Benefits
- High Load Capacity: The deep groove raceway and robust construction enable it to handle significant radial dynamic loads (6677 lbf) and radial static loads (4856 lbf).
- Optimized Cage Design: The combination of brass (M) and polyamide (FF) cages contributes to stable operation and reduced friction, supporting a limiting speed of 11,000 rpm.
- Precision Engineering: Manufactured to ABEC 1 / ISO P0 tolerance standards with a CN radial internal clearance, ensuring smooth running and minimal vibration for general precision applications.
- Material Integrity: All core components (rings, balls, cage) are made from chrome steel, providing high hardness, wear resistance, and durability across a temperature range of -30°C to 120°C.
306MFF Bearing Typical Application Areas
This bearing is ideally suited for applications requiring reliable radial support and moderate to high speeds, including:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
