313S Bearing Product Overview & Core Advantages
The 313S is a single row deep groove ball bearing designed for reliable performance in general industrial applications. As a metric bearing with an open design, it excels in handling radial loads with high efficiency. Its construction from chrome steel ensures durability and consistent operation within a standard temperature range. The bearing features a CN radial internal clearance and ABEC 1 (ISO P0) tolerance class, making it a cost-effective and versatile solution for various machinery requiring robust and dependable rotational support.
313S Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 313S | Standard bearing designation, indicating the basic size series (3) and bore code (13). The 'S' suffix is not a standard designation in this context and may refer to a specific manufacturer's series or variant; please consult technical documentation for precise interpretation. |
| Open (No Seal/Shield suffix) | The bearing is supplied without seals or shields, allowing for higher speeds and easy re-lubrication, but requiring a clean operating environment. |
| ABEC 1 | ISO P0 | Specifies the tolerance class, indicating standard manufacturing precision suitable for most general applications. |
| CN | Denotes the standard radial internal clearance for normal operating conditions. |
| Lubrication: None | The bearing is supplied without grease, providing flexibility for the user to apply a lubricant suitable for the specific application. |
313S Bearing Structural Features & Performance Benefits
The performance of the 313S bearing is derived from its fundamental single row deep groove ball bearing structure. The deep groove raceways on both inner and outer rings enable it to handle significant radial dynamic load ratings (22,931 lbf) and radial static load ratings (20,233 lbf). The open design and chrome steel cage contribute to a high limiting speed of 5,300 rpm. Manufactured from high-grade chrome steel for both rings and balls, it offers excellent wear resistance and a long service life. The standard CN clearance ensures reliable performance under normal operating temperatures and fits. Being supplied un-lubricated allows for optimal lubricant selection based on specific speed, temperature, and environmental conditions, maximizing application flexibility.
313S Bearing Typical Application Areas
- Electric Motors and Generators
- General Industrial Machinery and Gearboxes
- Material Handling Equipment (e.g., Conveyor Pulleys)
- Agricultural Machinery
