6311-2RS1 N/C3 GJN Bearing Product Overview & Core Advantages
The 6311-2RS1 N/C3 GJN is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. Its primary advantages include robust radial load capacity and reliable operation, enhanced by its sealed construction. This bearing is designed for high reliability and long service life, making it an ideal choice for applications requiring consistent performance under standard operating conditions. Its compact design and standardized dimensions ensure easy integration into existing machinery.
6311-2RS1 N/C3 GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6311 | Basic bearing series, indicating a medium series deep groove ball bearing with a 55mm bore. |
| 2RS1 | Features contact seals on both sides, providing superior protection against contaminants and retaining lubricant. |
| N | Snap ring groove on the outer ring, enabling simplified axial location within a housing. |
| C3 | Specifies a greater than normal radial internal clearance, suitable for applications with thermal expansion or heavy interference fits. |
| GJN | Indicates the use of a polyamide cage, which offers low weight, quiet operation, and excellent performance at moderate speeds. |
6311-2RS1 N/C3 GJN Bearing Structural Features & Performance Benefits
- Sealed & Protected Design: The 2RS1 double-contact seals effectively shield the bearing internals from dust, moisture, and other contaminants, while also retaining lubricant. This design significantly enhances bearing life and reliability in harsh environments.
- Optimized Internal Clearance: The C3 radial clearance provides operational stability in applications prone to thermal expansion or where heavy interference fits are used, preventing premature failure due to excessive preload.
- High-Speed Cage: The GJN polyamide (plastic) cage ensures smooth operation, reduced friction, and is well-suited for the bearing's limiting speed, contributing to lower noise and vibration levels.
- Robust Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing delivers a high dynamic and static radial load rating, ensuring durability and performance under significant mechanical stress.
- Simplified Mounting: The snap ring groove (N suffix) on the outer ring allows for secure and straightforward axial positioning, reducing assembly complexity and cost.
6311-2RS1 N/C3 GJN Bearing Typical Application Areas
This versatile bearing is commonly specified in a wide range of industrial machinery, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (Conveyors)
- Agricultural Machinery
- General Industrial Machinery requiring reliable radial support
