310NR/C3 Bearing Product Overview & Core Advantages
The 310NR/C3 is a single row deep groove ball bearing designed for robust performance in industrial applications. This metric bearing excels at handling primarily radial loads and offers reliable operation due to its standardized ABEC 1 (ISO P0) tolerance class. A key distinguishing feature is the snap ring fitted on the outer ring, which simplifies axial location and housing design. The C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used, ensuring consistent performance under varying operational conditions.
310NR/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 310 | Standard bore diameter series designation |
| NR | Outer ring features a snap ring groove for simplified axial positioning |
| C3 | Radial internal clearance greater than normal, suitable for applications with thermal gradients or interference fits |
310NR/C3 Bearing Structural Features & Performance Benefits
- High Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing delivers a radial dynamic load rating of 14,478 lbf and a static load rating of 11,690 lbf, ensuring durability under significant stress.
- Simplified Assembly: The integrated snap ring on the outer ring eliminates the need for complex housing shoulders or end caps, reducing assembly time and cost.
- Operational Flexibility: The C3 clearance accommodates shaft and housing expansions, preventing preload and potential bearing seizure in high-temperature or high-speed environments.
- Wide Temperature Range: Capable of operating in temperatures from -30°C to 120°C, making it versatile for various industrial climates.
- Open Design & Custom Lubrication: The open seal type allows for the application of specialized lubricants tailored to specific operational needs, though it requires a clean operating environment.
310NR/C3 Bearing Typical Application Areas
