6313-ZNR/C3 Bearing Product Overview & Core Advantages
The 6313-ZNR/C3 is a single row deep groove ball bearing engineered for high-performance industrial applications. This shielded bearing features a snap ring groove on its outer ring, enabling secure axial location within a housing without complex machining. Its optimized C3 radial internal clearance makes it exceptionally suitable for applications with thermal expansion or where interference fits are used, ensuring stable operation under varying thermal conditions. Designed for radial load capacity and moderate speeds, it offers a robust solution for demanding environments.
6313-ZNR/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| ZNR | Z: Non-contact steel shield on one side NR: Snap ring groove with snap ring fitted on outer ring |
Provides contaminant protection while maintaining low friction. The snap ring enables secure axial positioning and simplifies housing design. |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion and interference fits, preventing preload and ensuring smooth operation in thermally demanding applications. |
6313-ZNR/C3 Bearing Structural Features & Performance Benefits
- Optimized Internal Geometry: Precision-engineered raceways and ball complement provide high radial load capacity and smooth operation.
- Snap Ring Location: The fitted snap ring (outer diameter: 149.7mm) provides positive axial location, eliminating the need for complex housing shoulders and reducing assembly time.
- Shielded Protection: The non-contact steel shield (Z-type) effectively retains lubricant and excludes larger contaminants without significantly increasing friction or temperature.
- C3 Internal Clearance: This specific clearance group is ideal for applications with expected temperature differentials between the inner and outer rings, or where press fits are used, preventing binding and reducing operational noise.
- High-Quality Materials: Manufactured from chrome steel for rings, balls, and cage, ensuring durability, consistent performance, and long service life under standard industrial conditions.
6313-ZNR/C3 Bearing Typical Application Areas
The 6313-ZNR/C3 is ideally suited for a wide range of industrial machinery and equipment where reliable radial load support and simplified axial location are required. Key sectors include:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
