313NR/C3 Bearing Product Overview & Core Advantages
The 313NR/C3 is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This open-type bearing is characterized by its high radial load capacity and precise metric dimensions (65mm bore, 140mm OD). A key structural feature is the snap ring fitted on the outer ring, which provides secure axial location within the housing, simplifying assembly and enhancing operational stability. Manufactured to ABEC 1 | ISO P0 tolerance standards with a C3 radial internal clearance, it is an ideal solution for applications requiring reliable performance under varying thermal and load conditions.
313NR/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| NR | Snap Ring Groove | Facilitates secure axial positioning and simplifies housing design, eliminating the need for complex end covers. |
| C3 | Greater than Normal Radial Internal Clearance | Accommodates thermal expansion in applications with high operating temperatures or heavy loads, preventing premature failure due to clearance loss. |
313NR/C3 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The single row deep groove construction, combined with chrome steel rings and balls, provides a high radial dynamic load rating of 22,931 lbf and a static load rating of 20,233 lbf, ensuring durability and resistance to deformation under significant stress.
- Precision & Stability: Manufactured to ABEC 1 (ISO P0) tolerance class with tight bore and outside diameter tolerances, this bearing guarantees smooth, consistent operation and minimizes vibration.
- Simplified Assembly & Location: The integrated snap ring (NR) on the outer ring acts as a positive locating feature, streamlining the installation process and providing reliable axial security within the housing.
- Versatile Operating Range: With a temperature range of -30°C to 120°C and a C3 clearance, it is well-suited for applications subject to thermal fluctuations.
313NR/C3 Bearing Typical Application Areas
This bearing is widely used in various industrial sectors due to its robust construction and locating feature. Common applications include:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (Conveyors, Pulleys)
- Agricultural Machinery
