313MF Bearing Product Overview & Core Advantages
The 313MF is a high-performance single row deep groove ball bearing engineered for demanding industrial applications. This open-type bearing is designed to primarily accommodate high radial loads while also handling moderate axial loads in both directions. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers reliable precision and consistent operation. Its robust construction and optimized internal geometry contribute to its high limiting speed and long service life, making it an excellent choice for applications requiring dependable performance under continuous operation.
313MF Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 313MF | Standard bearing designation indicating metric dimensions: 65mm bore, 140mm OD, 33mm width. |
| Open | No seals or shields, allowing for higher speeds and facilitating custom re-lubrication. |
| CN | Standard radial internal clearance for normal operating conditions. |
313MF Bearing Structural Features & Performance Benefits
- High Load Capacity: The deep groove raceway and single-row design are optimized to support significant radial dynamic load ratings of 22,931 lbf and radial static load ratings of 20,233 lbf, ensuring durability under heavy loads.
- Precision Engineering: Built to ABEC 1 | ISO P0 tolerance class with tight dimensional tolerances on the bore, outside diameter, and width for consistent performance and easy installation.
- High-Speed Capability: The open design and chrome steel cage contribute to a high limiting speed of 5,300 rpm, suitable for rapid rotation applications.
- Material Integrity: All core components—rings, balls, and cage—are manufactured from high-grade chrome steel, providing excellent hardness, wear resistance, and dimensional stability across the operating temperature range of -30°C to 120°C.
- Versatile Lubrication: Supplied without lubrication, allowing end-users to select the optimal grease or oil based on specific application requirements for speed, temperature, and load.
