313M Bearing Product Overview & Core Advantages
The 313M metric ball bearing is a single row deep groove ball bearing engineered for superior performance in demanding applications. Designed primarily to accommodate radial loads, this open-type bearing offers high reliability and consistent operation. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures precise running accuracy, making it an ideal choice for general industrial machinery where cost-effectiveness and dependable performance are paramount. Its robust construction provides excellent durability and a long service life.
313M Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 313 | Standard bearing series designation, indicating the size and dimensions (65mm bore, 140mm OD, 33mm width). |
| M | Signifies that the bearing is made from Chrome Steel for both rings and components, offering high strength and wear resistance. |
Note: The absence of additional suffixes indicates an open (unsealed) design with no pre-applied lubrication.
313M Bearing Structural Features & Performance Benefits
- High Load Capacity: The single row deep groove raceway and high-quality chrome steel construction enable a high radial dynamic load rating of 22,931 lbf and a radial static load rating of 20,233 lbf, ensuring reliable performance under significant stress.
- Precision Engineering: Manufactured to ABEC 1 (ISO P0) tolerance class with a CN radial internal clearance, this bearing provides smooth, low-vibration, and low-noise operation, which is critical for maintaining machinery accuracy.
- Optimized for Speed: With a limiting speed of 5,300 rpm, it is suitable for a wide range of high-speed applications. The chrome steel cage ensures stability and integrity at these rotational velocities.
- Material Integrity: All core components—rings, balls, and cage—are constructed from chrome steel, providing consistent hardness, excellent resistance to wear, and a broad operating temperature range of -30°C to 120°C.
313M Bearing Typical Application Areas
The 313M bearing is versatile and finds use in numerous industrial sectors, including:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Industrial Pumps and Fans
