310 NA/C3L Bearing Product Overview & Core Advantages
The 310 NA/C3L is a single row deep groove ball bearing engineered for exceptional radial load capacity and reliable performance in demanding industrial applications. This open-type bearing features a C3 radial internal clearance and is constructed entirely from chrome steel for superior durability. Its design ensures stable operation across a wide temperature range and is ideal for applications requiring precise ABEC 1 (ISO P0) tolerance. The inclusion of a snap ring groove facilitates secure axial positioning during installation.
310 NA/C3L Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 310 | Standard bearing series designation, defining the basic dimensions (50mm bore, 110mm OD, 27mm width). |
| NA | Indicates the bearing has a snap ring groove on the outer ring for simplified axial location. |
| C3 | Specifies a greater than normal radial internal clearance, suitable for applications with thermal expansion or where interference fits are used. |
| L | Identifies the snap ring itself, which is supplied with the bearing for immediate installation. |
310 NA/C3L Bearing Structural Features & Performance Benefits
- High Radial Load Capacity: The single row deep groove construction is optimized to handle significant radial dynamic loads (14,478 lbf) and static loads (11,690 lbf), ensuring long service life under heavy-duty conditions.
- Enhanced Operational Stability: The C3 clearance provides extra space between rolling elements and raceways, accommodating shaft expansion and misalignment, which is critical in high-temperature or high-speed environments.
- Simplified Installation and Security: The integrated snap ring groove and supplied ring allow for secure axial positioning within a housing, reducing assembly complexity and preventing creep.
- Robust Material Construction: All critical components—inner ring, outer ring, balls, and cage—are manufactured from high-grade chrome steel, offering excellent resistance to wear and fatigue.
- Broad Application Suitability: With a limiting speed of 7,000 rpm and an operating temperature range from -30°C to 120°C, this bearing is versatile for various industrial settings.
