310 NAR/C3L Bearing Product Overview & Core Advantages
The 310 NAR/C3L is a single row deep groove ball bearing designed for high-performance industrial applications requiring robust radial load capacity. This open-type metric bearing features a generous C3 radial internal clearance, making it exceptionally suitable for applications with thermal expansion or where interference fits are used. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers reliable precision and consistent operation. Its construction from high-grade chrome steel for all critical components ensures durability and a long service life under demanding conditions.
310 NAR/C3L Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance & Advantage |
|---|---|---|
| N | Snap Ring Groove on Outer Ring | Facilitates secure axial location and simplified bearing mounting within a housing, reducing assembly time and cost. |
| AR | Snap Ring Included | Supplied with the snap ring, providing a complete and ready-to-install solution. |
| C3 | Greater than Normal Radial Internal Clearance | Accommodates shaft and housing fits that cause clearance reduction, and is ideal for applications with significant temperature variations. |
| L | Light Preload | Provides minimal preload to increase bearing rigidity and reduce noise/vibration in precision applications. |
310 NAR/C3L Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The single row deep groove construction and chrome steel components are engineered to handle significant radial loads (Dynamic: 14,478 lbf, Static: 11,690 lbf), providing stable and rigid support for rotating shafts.
- Optimized for Thermal & Fit Conditions: The C3 clearance is a critical feature that prevents bearing seizure in applications prone to thermal expansion or where tight interference fits are used on both inner and outer rings.
- Simplified Mounting & Axial Security: The integrated snap ring and groove (OD: 116.6 mm) eliminates the need for complex housing shoulders or end caps, ensuring the bearing remains securely positioned axially.
- Versatile Operating Range: With a temperature range of -30°C to 120°C and a limiting speed of 7,000 rpm, this bearing is suitable for a wide array of industrial environments and operational demands.
310 NAR/C3L Bearing Typical Application Areas
The 310 NAR/C3L is ideally suited for applications requiring secure mounting and compensation for thermal effects. Common uses include:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Fans and Blowers
- Agricultural Machinery
- Material Handling Conveyors
