310NR Bearing Product Overview & Core Advantages
The 310NR metric ball bearing is a single row deep groove ball bearing engineered for robust radial load applications. This open-type bearing features a snap ring fitted on the outer ring, providing secure axial location within a housing and simplifying assembly. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers reliable performance for general industrial use. Its construction from high-grade chrome steel ensures durability and a long service life across a wide temperature range.
310NR Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 310 | Standard bore diameter code for a 50mm bore bearing. |
| NR | Signifies a snap ring groove and fitted snap ring on the outer ring for axial location. |
310NR Bearing Structural Features & Performance Benefits
- Simplified Housing Design: The integrated snap ring eliminates the need for complex housing shoulders or end caps, reducing manufacturing costs and assembly time.
- High Radial Load Capacity: The single row deep groove construction is optimized to handle significant radial dynamic and static loads (14,478 lbf / 11,690 lbf).
- Standard Precision & Clearance: Built to ABEC 1 (ISO P0) tolerance with CN group radial internal clearance, ensuring consistent and reliable operation for most industrial applications.
- Versatile Material & Temperature Range: All-steel construction (chrome steel rings, balls, and cage) provides strength and reliable performance from -30°C to 120°C.
310NR Bearing Typical Application Areas
This bearing is ideal for applications requiring secure axial location and handling primarily radial loads. Common uses include:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Material Handling Conveyors
- Agricultural Machinery
- General Machinery with snap ring housing designs
