314 NR Bearing Product Overview & Core Advantages
The 314 NR is a single row deep groove ball bearing designed for robust performance in demanding industrial applications. Engineered to primarily accommodate radial loads, this bearing features a snap ring on its outer ring, which simplifies housing design and provides secure axial location. Manufactured from high-grade Chrome Steel with a Stainless Steel cage, it offers excellent durability and reliable operation. Its open design and P0 tolerance class make it a versatile and cost-effective solution for a wide range of machinery, ensuring high reliability and long service life.
314 NR Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 314 | Basic bearing designation, indicating the bearing size and series. |
| NR | Signifies the bearing is fitted with a snap ring (retaining ring) on the outer ring. This feature acts as an outer ring locating feature, facilitating easier assembly and providing a positive axial stop within the housing. |
314 NR Bearing Structural Features & Performance Benefits
- Snap Ring Design: The integrated snap ring eliminates the need for complex housing shoulders or separate retaining devices. This simplifies housing machining, reduces assembly time, and ensures secure axial positioning of the bearing, enhancing overall system rigidity.
- High Load Capacity: The single row deep groove construction is optimized to handle significant radial loads, with a dynamic load rating of 25,628 lbf and a static load rating of 22,931 lbf.
- Precision & Reliability: Manufactured to P0 tolerance class with a standard CN radial internal clearance, this bearing provides consistent performance and interchangeability. The Stainless Steel cage ensures high strength and corrosion resistance for the cage component.
- Material Integrity: Both rings and balls are made from Chrome Steel, providing high hardness, wear resistance, and a long operational lifespan under typical operating conditions.
- Versatile Operation: With an open seal type, it is suitable for applications where external lubrication is provided. The operational temperature range is from -30°C to 120°C.
314 NR Bearing Typical Application Areas
This bearing is ideally suited for applications requiring a reliable, easily mounted radial bearing solution. Common uses include:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Fans and Blowers
- Agricultural Machinery
- Material Handling Equipment (e.g., conveyor pulleys)
- General Industrial Machinery where a snap ring simplifies housing design
