313NJ/C3 Bearing Product Overview & Core Advantages
The 313NJ/C3 is a single row deep groove ball bearing designed for robust performance in demanding industrial applications. This metric bearing features a snap ring groove on its outer ring, providing secure axial location within a housing. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers reliable operation and consistent performance. A key characteristic is its C3 radial internal clearance, which makes it suitable for applications with elevated operating temperatures or where interference fits are used, ensuring optimal performance under such conditions.
313NJ/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 313 | Basic bearing series and size designation. |
| NJ | Indicates the bearing has a snap ring groove on the outer ring. This feature aids in axial location and simplifies housing design. |
| C3 | Specifies a radial internal clearance greater than the standard CN group. This is crucial for applications involving thermal expansion or tight interference fits. |
313NJ/C3 Bearing Structural Features & Performance Benefits
- Robust Load Capacity: Built with chrome steel rings, balls, and cage, this bearing offers a high radial dynamic load rating of 22,931 lbf and a radial static load rating of 20,233 lbf, ensuring durability under significant radial loads.
- Simplified Assembly and Axial Location: The integrated snap ring groove eliminates the need for complex housing shoulders or end caps, reducing assembly time and cost while providing secure axial positioning.
- Operational Flexibility: The C3 clearance provides operational stability in applications prone to thermal expansion, preventing binding and reducing friction and heat generation.
- Open Design & Versatile Lubrication: As an open bearing, it allows for the use of various lubrication methods tailored to specific application needs, supporting a wide temperature range from -30°C to 120°C.
