| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 313 | Standard Bearing Series & Size Designation | Defines the core dimensions: 65mm bore, 140mm OD, 33mm width. |
| MG | Machined Brass Cage | Indicates a robust, machined brass cage for superior strength, guidance, and performance at high speeds and temperatures. |
| Open | Seal Type | No built-in seals, allowing for custom lubrication solutions and easy re-lubrication, ideal for controlled environments. |
313MG Bearing Structural Features & Performance Benefits
Optimized Deep Groove Geometry: The raceway design facilitates smooth operation and efficient handling of radial loads, with a capacity for moderate axial loads in either direction.
Machined Brass Cage (MG): This cage material provides high mechanical strength, excellent dimensional stability, and reliable ball guidance, which is critical for maintaining performance at the bearing's high limiting speed of 5,300 rpm.
High-Grade Chrome Steel Construction: Both the rings and balls are made from chrome steel, ensuring high load capacity, wear resistance, and long service life. The radial dynamic load rating is 22,931 lbf and the static load rating is 20,233 lbf.
Precision Engineering: Manufactured to ABEC 1 / ISO P0 tolerance class, this bearing guarantees consistent quality, low vibration, and minimal noise levels for smooth operation.
313MG Bearing Typical Application Areas
The 313MG is ideally suited for a wide range of industrial applications requiring reliable performance under radial loads and moderate speeds, including:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment (Conveyors, Pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring a robust, open-bearing solution.
