6312-2RS1/C4 Bearing Product Overview & Core Advantages
The 6312-2RS1/C4 is a single row deep groove ball bearing designed for robust performance in demanding applications. This sealed bearing excels at handling primarily radial loads and offers reliable operation due to its high-quality construction and generous internal clearance. Its key advantages include high load-carrying capacity, effective sealing for contaminant exclusion, and a wide operating temperature range, making it a versatile and durable choice for industrial machinery.
6312-2RS1/C4 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6312 | Basic Bearing Series & Size | Denotes a medium-duty, single row deep groove ball bearing with a 60mm bore, 130mm OD, and 31mm width. |
| 2RS1 | Contact Seals on Both Sides | Features nitrile rubber (NBR) seals that make firm contact with the inner ring, providing superior protection against contaminants and moisture retention of lubricant. |
| C4 | Greater than Normal Radial Internal Clearance | Indicates a larger internal clearance than standard (C0), making it suitable for applications with significant thermal expansion, such as in electric motors or high-temperature environments. |
6312-2RS1/C4 Bearing Structural Features & Performance Benefits
Optimized Sealing for Reliability: The 2RS1 contact seals are the cornerstone of this bearing's durability. They effectively shield the chrome steel rolling elements and raceways from dust, dirt, and moisture, significantly extending service life and enabling operation in harsh conditions. This design supports the bearing's wide temperature range of -30°C to 120°C.
High Load Capacity and Rigidity: Manufactured from high-grade chrome steel for both rings and balls, the bearing offers a high radial dynamic load rating of 18,412 lbf and a static load rating of 11,735 lbf. The deep groove raceway and robust chrome steel cage contribute to stable operation under substantial radial loads.
Application-Tailored Internal Clearance: The C4 clearance is a critical feature for applications where thermal expansion of the shaft or housing is a concern. This prevents preload and potential binding, ensuring smooth running and preventing premature failure.
6312-2RS1/C4 Bearing Typical Application Areas
The 6312-2RS1/C4 is ideally suited for a wide range of industrial equipment requiring reliable, sealed bearings with high radial load capacity. Common applications include:
- Electric Motors and Generators (benefiting from the C4 clearance for thermal management)
- Industrial Gearboxes and Transmissions
- Material Handling Conveyors
- Agricultural Machinery
- Pumps and Fans
