6312-2RS1/C4GJN Bearing Product Overview & Core Advantages
The 6312-2RS1/C4GJN is a sealed single row deep groove ball bearing engineered for robust performance in demanding applications. Its primary advantage lies in its ability to efficiently handle radial loads while offering reliable operation across a wide temperature range. Featuring integral contact seals and a generous C4 radial internal clearance, this bearing is designed for applications where thermal expansion is a factor, ensuring consistent performance and high reliability.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6312 | Basic bearing series; 60mm bore, 130mm OD, 31mm width. |
| 2RS1 | Bearing is fitted with two rubber contact seals on both sides, providing superior protection against contaminants. |
| C4 | Specifies a greater than normal radial internal clearance, suitable for applications with significant thermal gradients or where interference fits are used. |
| GJN | Indicates the bearing is lubricated with a Polyurea Thickener Grease, offering a wide operating temperature range and long service life. |
6312-2RS1/C4GJN Bearing Structural Features & Performance Benefits
- Robust Sealing: The 2RS1 rubber contact seals effectively retain lubrication and exclude moisture, dust, and other contaminants, significantly enhancing bearing service life in harsh environments.
- Optimized Internal Clearance: The C4 radial clearance accommodates shaft expansion and interference fits, preventing operational issues caused by thermal expansion and ensuring smooth running under varying temperature conditions.
- High-Quality Materials: Constructed entirely from chrome steel for rings, balls, and cage, this bearing delivers high strength, durability, and resistance to wear.
- Ready-to-Use Lubrication: Pre-lubricated with GJN grease, the bearing is maintenance-free for its entire service life under normal operating conditions, simplifying installation and reducing long-term costs.
6312-2RS1/C4GJN Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Generators
- Industrial Gearboxes and Power Transmission Systems
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
- Pumps and Fans
