312MF Bearing Product Overview & Core Advantages
The 312MF metric ball bearing is a high-performance single row deep groove ball bearing designed for reliable operation in demanding industrial applications. Engineered to primarily accommodate radial loads, this open-type bearing offers excellent versatility. Its construction from high-grade chrome steel ensures durability and consistent performance. With a precision ABEC 1 (ISO P0) tolerance class, it provides dependable accuracy for a wide range of machinery, making it a robust and cost-effective solution for general industrial use.
312MF Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 312 | Standard bearing series designation, indicating the dimensional series (width and outer diameter relative to the bore). |
| M | Indicates the bearing is of metric dimensions. |
| F | Signifies a specific manufacturing or material specification, often related to the cage design or internal geometry. |
312MF Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and single row of balls provide a simple, effective, and reliable structure for handling significant radial dynamic load ratings up to 20,525 lbf.
- High Load Capacity: Manufactured from through-hardened chrome steel for both rings and balls, this bearing offers high resistance to wear and fatigue, supporting a substantial radial static load rating of 17,535 lbf.
- Optimized for Speed: The design and standard CN radial internal clearance contribute to stable operation, allowing a limiting speed of 6,000 rpm.
- Precision & Stability: The ABEC 1 (ISO P0) tolerance class ensures consistent running accuracy and minimal vibration, which is critical for the smooth operation of industrial equipment.
- Application Flexibility: The open seal type allows for custom lubrication regimes, making it suitable for various operational environments within its temperature range of -30°C to 120°C.
312MF Bearing Typical Application Areas
The 312MF bearing is ideally suited for a broad spectrum of industrial machinery where reliability and radial load capacity are paramount. Common applications include:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Conveyors
- Agricultural Machinery
- Pumps and Fans
- General machinery requiring a robust, standard-precision ball bearing.
