6314-ZNR/C3 Bearing Product Overview & Core Advantages
The 6314-ZNR/C3 is a high-performance single row deep groove ball bearing engineered for demanding industrial applications. Its core advantage lies in its integrated snap ring (ZNR) on the outer ring, which provides secure axial location within a housing, simplifying assembly and reducing the need for complex housing designs. The C3 radial internal clearance is optimized for applications with elevated operational temperatures or where interference fits are used, ensuring consistent performance and extended service life under varying thermal conditions. This bearing is designed to handle significant radial loads efficiently, making it a robust and reliable choice for a wide range of machinery.
6314-ZNR/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Model Suffix | Technical Meaning | Advantage |
|---|---|---|
| -ZNR | Snap Ring (fitted on the outer ring) | Provides positive axial location, simplifies housing design, and reduces assembly time and cost. |
| /C3 | Greater than normal radial internal clearance | Accommodates thermal expansion, prevents pre-loading from interference fits, and is ideal for high-temperature applications. |
6314-ZNR/C3 Bearing Structural Features & Performance Benefits
- Snap Ring Groove & Location: The bearing is supplied with a snap ring pre-fitted into a groove on its outer diameter. This feature acts as a positive axial locating device, preventing creep and simplifying the bearing housing to a simple bore, which lowers manufacturing costs.
- Robust Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing delivers a high dynamic load rating of 2338 lbf and an exceptional static load rating of 15332 lbf, ensuring reliable performance under heavy radial loads.
- Optimized Internal Clearance: The C3 clearance is a key performance feature. It allows for differential thermal expansion between the inner and outer rings, preventing binding and maintaining smooth operation in applications with significant temperature fluctuations.
- Shielded Design: The integral shields protect the bearing's internal components from large particulate contaminants, helping to preserve lubricant integrity and extend bearing life in challenging environments.
6314-ZNR/C3 Bearing Typical Application Areas
The 6314-ZNR/C3 is ideally suited for applications requiring secure axial location and robust performance. Common industries and equipment include:
- Electric Motors and Gearboxes: Where the snap ring provides a simple and effective method for housing the bearing.
- Industrial Pumps and Compressors: Benefiting from the high radial load capacity and the ability to handle thermal growth.
- Agricultural and Construction Machinery: Utilizing the bearing's durability and simplified mounting in rugged environments.
- Material Handling Systems: Such as conveyor pulleys and rollers, where reliable performance is critical.
